Is it normal that i let a guy grope me?

I'm a college students who lets this guy who goes to my school grope me and I enjoy it. He does this in public. He has also groped other girls and even fucked one in front of people.

I'm a 21-year-old virgin who really needs to get laid and realizing this, I asked him if he can teach me about hooking up.

I'm not interested in anything beyond oral sex with him and he said that we'll never be anything beyond really close friends. I just want to know what the hell I'm doing when I do lose my virginity.

I kissed him today and he said that I open my mouth too wide. I've only kissed two other guys before him and they said my kissing is average. Nothing special.

So, I basically asked him to help me get laid and do it right. Is this normal?
