Why don't I like anal sex?

If I say that I don’t like anal sex, it doesn’t mean that I don’t do it at all haha ​​But it really is! I think that my NOT love for anal sex arose from my first sad and rough experience. My partner didn't know how to do it right, so he lied to me to have fun! It was very painful, scary, but out of my stupid naivety I thought that it should be so! Now, of course, I already have anal sex only if I myself WANT IT! It rarely happens, but it happens haha
But the first time no one got pleasure... not even a guy
