Hi I'm 17 and my bf wants to go all the way bit I'm scared and I cant even masterbate so what will happen?
If your boyfriend wants to go all the way, but you're scared, you both need to sit down and talk about it. It sounds like you aren't ready, and he will understand. If not, then he isn't right for you. When you feel that it's time, start off slowly with other forms of sex than full sex. If you feel the need to stop, tell him. Good luck!
I agree, don't let him do anything you don't want him to. If he doesn't respect you, dump him. :)
