Do you think anal sex is wrong?

It all depends on your culture, in some anal sex is a normal act in both heterosexual and homosexual people. You only have to look at the Indian and Greek cultures and their art work to see this. At the end of the day it is what you and the person you are having sex with like, some like anal sex and would never do oral sex, with others it is the other way round, so enjoy what you do and just get on with life.
