Is it okay not to have anal sex?

It is totally okay if you don’t want to have anal sex. 

Many people simply don’t like anal sex. Some consider it gross, for others, anal sex conflicts with religious beliefs

Whatever the reason that drives your preference, always keep in mind that you should only do things you feel comfortable with. 

And if somebody ever tries to force you into sexual act of any kind, you should seriously think about whether that person really cares about you.

Know that you are definitely not alone.
