Sex drive.

For the year my boyfriend and I would go at it like cats and dog (having sex.) now we've hit the year and 7 months mark and we have sex once maybe twice a week, I know it seems minor but it worries me. He says it's because he has trouble finishing, and he doesn't want to have sex if he isn't going to finish because it's embarrassing. It's hard on me because I still have the sexie drive a rabbit. I know he isn't cheating for a fact but I'm worried about if I'm just not sexy enough anymore.
