First Serious Boyfriend

I have this problem, so I’m 17 and this is my first serious boyfriend and I’m his second girlfriend. We’ve been dating for almost 2 months. Just a couple weeks ago he started touching my private areas. For a while now he’s been telling me that he gets boners really easily. But I don’t do anything to make him get them so I’m a little confused. Anyways I don’t think I’m ready for him to be touching me or me touching him. I tried giving him hints that I don’t want him to touch me but I don’t think he gets it.

What should I do?
