Haven't had sex yet.

Hey. So I am 19 years old and am currently in a relationship with a 21 year old. It will be two months on Sunday (July 17) and we haven't done anything yet. We barely kiss! Our families are friends, so we've known each other for 14 or 15 years. It's a good thing we haven't done any sexual thing yet, right? I'm only asking because this isn't normal for me! I've had 3 serious relationships before this and within three months of dating, we have already had sex or done things related to that topic. It just feels really weird... Any advice? It'd be much appreciated!
