Self Concious

okay, ladies...I've been struggling alot recently, because I've never been able to smell, like from birth, I haven't ever been able to smell. So, I get self conscious just thinking about a boy going down on me. When I was with my ex( we dated for over a year) I kept that I couldn't smell from him for months because I was so embarrassed about it, but he was okay with it, just a little shocked. But he had been going down on me for a while before I even told him about my smelling problem. But, anyways the point of this is that I'm extremely self conscious about my vagina and whether or not it smells or not. And my ex was too nice, so even if it smelled, he wouldn't of ever told me. So, the whole point of this is how am I supposed to know if it smells or not if I can't smell?
