I've never really felt the urge or desire to want to have sex; it's just not something I need for a relationship to work (I've been in one for about three years now). Today I just nonchalantly told a few family members I was next to about how I identified as asexual. And they laughed and called me crazy, because "sex is part of being attracted to someone." I tried to explain that there's a difference but they won't listen. Any suggestions?
