My boyfriend wants more sex, but I don't know if I want more sex?

I love my boyfriend don't get me wrong, but lately he is wanting more sex than usual. We have sex 2 to 3 times a week but lately he wants more sex than 2 to 3 times a week. I want to fulfill his need for sex but I don't know if I want more sex for me? I feel that if I don't give into having more sex that he'll leave and never come back. Should I allow him to have more sex than 2 to 3 times a week or should I have a serious talk with him about how good our sex life is now that we don't need to boost it up? He's great and all, but I just don't think we need a boost in our sex life with one another.
