We've been dating for a year though. This seems like I'm overreacting. He's a good guy. I think he just wanted to try something different. I promise he doesn't hurt me
So this has been a recent sort of topic in your relation then? Somebody or something must have given him the idea for it then, and gotten him all excited. I've known college guys in my day, heck, I've been one, and as a species, I wouldn't say they are well known for their macchiavelian planning and their willingness to wait for over a year to force/persuade an underage woman into sexual activities she isn't asking for.
It doesn't excuse this behavior though, and certainly not the pressure he's putting on you to comply to his wishes. But you seem unwilling to break your relationship off over this, so I have to assume you had a good time so far and you are convinced he's a decent guy, present circumstances not considering.
I still advise against continuing your relationship with him, but if you want to continue with it nevertheless, make sure to state explicitly, and emphatically, that you are not willing to have sexual intercourse in any shape or form with any of his friends, period, and that this is an absolute deal breaker for you. Then tell him to stop asking about it, and furthermore tell him to make his friends stop casting innuendo your way as well. If he is the decent guy underneath you claim he is, he should accede to your wishes. If he doesn't, you should call it quits, period.
