I want my bf so bad 😝😍😫💕

I'm 17 (18 in January) and my boyfriend is 21, we've decided to wait until I at least turn 18 to have sex and I'm loving taking it slow and really getting to know him but holy fuck I wanna fuck him. I have to put this here because my "best friend" doesn't even approve of me being with him because he's older, yet everyone else I've talked to said it's just a number.
