Feeling pleasure from receiving anal sex is first mental and then physical. I will first talk about the mental aspect of receiving anal sex. I explained in my "How to give great blowjobs" writing that swallowing a man's cum is great for people who like to be dominated or humiliated because it allows you to feel used or allows your lover to mark his territory with his sperm. That submissive mentality is what excites people like me who feel that way. Taking a man's erect penis in your ass has the same erotic effect. Then if you go a step further and take another man's cum in your ass, not only do you feel the physical pleasure from the warm sticky texture but the mental fantasy from allowing a man to breed you or use you as an object that pleasures his cock and accepts his seed.
That mental stimulation of being dominated is why so many women do not enjoy anal sex. They cannot get past that "afraid it is going to hurt" mentality because they can already get "breeded" naturally or be dominated vaginally. If your mentality is "It's his birthday so I want to do something special for him no matter how much I don't want to do it," then you already will not enjoy it as the receiver. Men or women who love to be dominated or humiliated are those who enjoy anal sex and the more you are dominated, the better it is. This is why we love bigger cocks, black cocks, large men, being a "bitch," calling someone daddy, etc. Those references show you are completely submitting. Submissives think, "If I can take an 8 inch cock in my ass, then I will really be dominated if that cock is 12 inches and black." Mentally, this is why men like to get fucked in the ass.
Another mental aspect from receiving anal sex from a submissive's point of view is not only knowing your partner is using your ass for his pleasure but you have to ability to satisfy him. Just knowing you have that power is also an aphrodisiac. Your power also lies in the fact that not only you can accept his erect dick in your ass but you can do it well. That ability will keep him coming back for more. Nothing will be make him happier than if you can take all of his dick without hesitation. A well hung man usually cannot fit his entire penis in a vagina without pain, but he can put all of it inside a rectum. Your partner loves the power aspect of making you squirm a little or yell out when he pounds your hole but he will not like it if he can't fit all of himself in you or you keep pulling off of it because you cannot handle the pain. I have had 5 inch cocks in me as well as 12 inch. I allow him to put it all inside me and allow him to fuck his style until he has a strong finish. That is the key to being a good bottom.
If done properly, most of the time the person receiving anal sex, can be pleasured physically as well. I enjoy jacking off while getting screwed in the ass. I know how my body works and use the guy's cock to my advantage as a woman would do masturbating with a dildo. You just have to get lots of practice to get the right feel and get yourself off the way that gives you the most pleasure as your riding or getting pounded. It doesn't happen often, but I have shot my load from just being fucked without using my hands. I think the mood and his dick size has to be just right for that to happen. I think the perfect dick size for the receiver to gain pleasure is 8 to 9 inches in length and about 4-5 inches in girth with a slightly larger than average head. This size cock fits snug in you and the head messages your prostate just enough to give you that physical pleasure you need to get off. I have taken and enjoyed cocks of all sizes but to get your own pleasure, I feel those measurement criteria is what works best for me but it also depends on the size of the man receiving it.
Overall Preparation
Once you have overcome the mental obstacle of anal sex, it is time to proceed. If you are a male, you need to think a little bit like a women in the traditional sense. You are keeping your ass prepared for him to enter at a moment's notice. You need to keep your body's digestive system regular, your ass clean, well groomed, and tight. Keeping true to these factors will allow you to accept his cock no matter the time of day and on a regular basis. Men love when you are always ready.
Staying regular means keeping your digestive system in order. You need to eat small portions of protein and fiber which will keep your bowel movements regular. It is still a good idea to use enemas before you engage in anal sex but it is not always feasible if you engage spontaneously on occasion. Using enemas can also be used in foreplay by having your partner insert it and discharge its contents inside you. I do NOT get into the brown stuff so I like to clean up in private to get myself ready for cock.
If you're in a relationship where your man wants sex on a daily or every other daily basis, then there will be times where you cannot flush yourself out with an enema. During my junior year in college, I lived with a guy named Bob, and since he would only get to see his girlfriend every other weekend, he wanted to fuck, get a blowjob, or sometimes both, every day except the weekends she was visiting. I had my own room and there were many mornings he would wake up with that raging hard on or even come into my room in the middle of the night wanting to fuck my ass. I didn't always have time to use an enema, so he would lube up his rock hard, 9 inch, large headed dick and once he got it in me, he would pump away and usually it didn't take long before he unloaded his spunk up me.
Because I kept myself regular, most of the time, there were no issues but I always had a towel handy just in case. Never have anal sex without a towel. It can have many uses such as wiping the lubrication off your hands before you or your lover get started. The towel can be used for any santorum liquids expelled during anal sex. It can be used to wipe off your lover's cock in the middle of anal sex if you decided to suck it to finish him off (you really don't have time for that if he wants to pull out and cum in your mouth). Of course, the towel can be used to wipe the cum and lubrication out of your ass after you have finished. A towel has many functions and is always needed during anal porn videos
Keeping clean also refers to your outer asshole as well. I have discussed in length about enema use in my first writing and in this one, so keeping a clean inner rectum has been covered. A clean outer section is also a must. It is a good idea to always have handy/baby wipes around. You can carry a few around in a zip lock bag for emergencies. If you meet someone at a club or pub and you end up in the back seat of his car getting your ass fucked, you don't want to be caught "dirty."
Keeping your ass well groomed means keeping it groomed according to your man's taste. To me, it means keeping my ass muscular, shaved, and having a good complexion. I work out by doing many stair steps and elliptical machine running to keep my ass in good shape. I like to keep my ass hairless. I shave or have it waxed on a regular basis. A good complexion on your ass is important so you do not have zits or blemishes. I use special moisturizing cleaners to keep my ass blemish free. In my experiences, if a guy sees you have a muscular, smooth ass, he will more likely want to plunge his fat cock in it. You have to be willing to put in some maintenance. Keeping your ass in shape will also allow you to heighten your sensitive pleasure nerves and allow you the stamina to accept dick for longer periods of time.
Keeping your ass tight not only refers to keeping your ass and legs in shape it also refers to your hole. There are some guys who enjoy having their ass dominated so much they are constantly pushing the envelope with larger things such as fisting and humongous dildos. A man's asshole is resilient and can recover from large cocks but eventually having gigantic objects shoved in there consistently will have ill effects, especially as you age. It is perfectly fine using dildos and butt plugs on yourself when you are in need of that ass fucking tube sensation. Riding and bouncing on the occasional large, black, real feel, dildo while jacking off is fine and great but remember you want to keep your asshole warm and tight for your lover's hard dick and the way to do this is by using your ass sensibly.
