Sex problems

I have been with my boyfriend six months now. Usually we have sex few times in a week, mostly if I make the first move. I would like to have sex every day, but he doesn't. Luckily I have sex toys. We have talked about issue and I think that he is not confident enough and is constantly asking (and joking) about my previous sex experiences (he has none before me). I avoid telling, because I doesn't want to make him insecure. He also jokes that I'm going to cheat on him when I go to parties. I just feel, that we are not on the same line, what comes to the sex. Otherwise our relationship is okay, thought he is always on his computer and very rarely visits my flat, we are always hanging in his house. I hope that things get better.
