Personally i don't encourage virginity before marriage because, there are a lot of things people dont know about themselves sexually before they get married and that can and will lead to a breakup in marriage..
I have had experienced where, the partner may not like longer sex and foreplays, or some don't like oral sex and that is what the partner wants more, so if you dont know these things before marriage, you might end up have a cheating partner, I think its best to know all these things and accept them before marriage, then you know what you are already getting into.
