Bf Wants Sex But I’m Not Ready...

I’m in grade 10 dating a grade 12. We’ve been together for 7 months and I give him oral sex all the time. My bf asks me pre often if I wanna have full sex. In our whole relationship he’s asked at least 10 times. It’s starting to bother me that he keeps asking to have sex. I’m a virgin and I don’t feel ready at this time to loose that. Ik I want to soon and I want it to be with him but he’s so persistent and even tho he says “I’ll wait till ur ready just let me know” he still continues to ask me every once in a while. It’s stressing me out cz I want to give him what he wants and make him happy but it’s turning me off that he keeps asking to have sex when he knows I don’t want to. My bf doesn’t even eat me out and expects me to give him sex. No. I need some advice or opinions please.
