Well, I have been dating with this guy for over 5 months and we've been friends for 3 years. I'm 21 and he's 20. On the third month of our relationship, he went under my bra while we were making out. I enjoyed it really much but afterward every time we kiss he grabbed and squeezed my boobs; which started to discomfort me. So I told him that maybe we should take it a bit easy and he reacted in a very mature way. Since then, he never ever touched my boobs. So my question is, what if I want his hands on me again one day? How should I let him know? He's my first boyfriend /but I'm not his first) so I'm quite inexperienced about this please help.
