Emotionally Absent BF.

Ok. So. I'm now a senior in high school (17) and I've been dating this fantastic boy since freshman year (16). He's a Grade A Neeeeeerdddd. But I love him. He's quiet, he listens, I listen, we can joke around but we can't really get around to the sexual part of the relationship. It's like there's never time or anything or he kinda just ends the sex talk. With both of my parents working from home and his mom at home all the time it's not like we can do it at each others house. And on top of that I just feel like he doesn't want to have sex, like at all. And I respect that. I'm not shallow enough to dump him because HE doesn't want to have sex but, I just feel like he's with me every way but emotionally. Huh huh. Advice??? Help??
