Not interested in sex

Hey girls just wondering is this normal.. So I've been with my boyfriend for about 5 months now. He's my first serious relationship (it's also long distance) I really like him but I feel like I have no desire to have sex.. I am a virgin and am on birth control for the simple reason that I'm a very paranoid person so I'd just rather not take any chances.. We do other things but I always feel completely satisfied from oral and feel like I don't want anything else?
