I can’t make out if you don’t want sex with your boyfriend because you don’t like men, or you don’t want sex because you are worried what he will think of your genitals because they look different.  Can you be a little clearer?

I would advocate being honest at all times within your relationships and to be open.  If you met a partner, don’t hide these things as this can create distrust within your relationship and  problems later down the road.  Whilst it isn’t good to rush into sex within a relationship, it is not practical to avoid it either in this day and age.  People do not necessarily ALL believe in sex after marraige because it is not all the time that people marry.  There are many couple that have been together for years outside of a marraige ceremony.  I think it is important to keep yourself reserved for the right time though just as anyone should without CAH.   Most partners worth their salt would want to be with you because of who you are anyway, and  such differences would be unimportant.  Although sex  plays a part in most  relationships with a partner, it is not the only thing that binds two people together in a long term relationship.
