Scared about sex

I’m a virgin and I’m rly scared about having sex. My boyfriend wants to have it and I said that I want to wait until I’m 16 (I will be in 7 months). He keeps talking about it and says that he’s ‘joking around’. I told him to stop joking and to his credit he has stopped (90% stopped🙄). I just really don’t want him to want me just for my body. I am scared that he is not respecting my feelings towards losing my virginity. I don’t know what to do. Any ideas??
