I think if you have an open attitude and prepare properly, you are much more likely to have a good experience. Being rough and aggressive is not a good way to start. For men, the prostate gland is supposed to do something that makes pleasure more likely. Women seem to do well enough without one.
It’s not to everyone’s taste, and if you don’t like the idea, you probably shouldn’t try it. In addition, it has a lot of social connotations that suggest it is something only really weak folks will do. No self-respecting person would ever do it is the conventional thinking on the subject, I believe.
If you can’t get past those kinds of idea, it won’t work for you.
Now as to the internet, I think there are certain tropes that have become standard. I think that anal implies that a woman is totally dominated especially when They show those gaping anal views as a demonstration of I know not what. I, personally, find those scenes very discomfiting.
In popular imagery, I think, anal is about power and dominance or submissiveness on the other side. It’s a kind of semi-forbidden thing, and I believe that a lot more guys want to do it with their girlfriends than the girlfriends want to do it with the guys. You have to be able to get past the social symbolism in order to even begin to give it a chance.
Since it is less common and has all these connotations, I think that some couples see it as being a very special thing. And, of course, many people enjoy giving their partners a good time and often they get off on their partner’s pleasure, whether that pleasure is physical or psychological.
Obviously, the anus is pretty tight and so this should give the man a more exciting experience, unless it makes him cum prematurely. So that is another attraction for men, anyway. I think some women like to use a dildo to do it to their partner, again, partly because of the forbiddenness of it, but also because of the symbolism of sharing the penetrating and receiving ends of the relationship. A man who is willing to do that for his partner is very desirable to some women, and if he learns to enjoy it, that can, probably, create a good experience for all.
This brings us to the realm of role play. Who is “man” and who is “woman.” Who penetrates and who is penetrated. Who is dominant and how they are dominant… or how they arrange some form of equality in the physical manifestation of the relations.
Hah! Bet you thought this was going to be much more prurient than it is. Sorry, Charlie.
