I don't know what to do

So like this guy that likes me( I like him) and I were talking. He's 15 and I'm 14. Anyway he was asking me if I'd ever have sex with him if we were in a long relationship. And I was like probably but like Idk right now. Then he asked me if I would give him head before we ever date if we did and I was like dude I'm a virgin I ain't done none of that. And I know that wasn't the answer he was looking for but like I really like him and I want it to work out so can u just help I don't know how to handle this problem he's just been like very distant ever since that's happened. And I know him we're friends he's not a fuckboy. I just don't know if I'm willing to do it. I don't know what to do. Or how to get our relationship back on track . Also I didn't know what group to put this in so
