Very few people.

Most people have never even thought about it but if you are born with a penis that means that you have a prostate. Most men will never get to experience the intense pleasure of an anal orgasm simply because they are ashamed of just the very idea of putting something in their butt. Then of course the fellows that enjoy being a bottom and eather don't believe that it exists or just gave up trying.

There doesn't seem to much advise on the whole thing because everyone is different and have various spots that is your buttons for getting the big one. I do suggest hours of work with your toys and experimenting with several styles and sizes. Myself I prefer a realistic seven or eight inch rubber dildo and hitting a few deep spots. After I get the first two or three small ones I will most likely start multiple ones that squirt up to a foot away from me. It can be incredible and very intense at this point if I push it further. I have almost passed out on the floor or the bed a few times and I am not sure but I might actually have blacked out for a bit and just don't remember.

I have never been able to get that far with a partner but I have come close a time or two with one very special man that is hung with a extremely special cock. It's probably a good idea to tell your partner or partners whom you are being sexually active with that you want to experience it and then work through some of what it takes together. This is something that I wish I had done.
