What on earth should a 21 year old guy do when he's so anxious about the "possibility" of remaining a virgin all his life, that his view on the issue is practically apocalyptic?

What should this guy do when his way of handling his fear is this...:

Guilting me about how he doesn't get laid, casually mentioning to me how he would love to sleep with me, and then physically pushing himself onto me even when I say stop? I'm pretty sure this ISN'T the way to get laid. By the way, begging isn't beneath him.

I understand I'm sexually open and flirtatious by nature, and we had hooked up once before a while ago, but I wasn't saying stop [over and over and over] in a joking manner when he was pushing himself onto me. I was quite serious.

The next day, when I told him I didn't like what he had been doing, this jerk went on to tell me that I didn't seem to be fighting back? [Seriously? Did I need to punch this kid in the face? Really, that line might as well been scripted in a bad teen movie. I kept telling him that so long as I had a boyfriend, I wasn't going to sleep with him!...But I guess that gave him too much hope.
My friends and I were reading our conversation online together, and we concluded he's developing the characteristics of an abusive boyfriend: He would guilt me, then treat me with no respect physically, tell me its my fault or come up with excuses for his bad behavior, then suddenly come back and tell me how much he needs me and cares for me and how he'll never do these things again....But they happen. Again.

Yeesh.

I got him to stop talking to me, but god damn! Does this kid have a serious issue? Should he see a therapist? To me, it seems to be about way more than getting laid....It's more anxiety and selfishness, in my opinion. Should he see someone for this?

Does this kid need serious help?

You really wouldn't see this coming. He's calm, cool, collected in person. A dorky engineering student who's only had 2 girlfriends, and obviously never got laid. He claims he'd go to the end of the earth for those he cares for, but clearly when his needs are in the way, his needs come first before anyone else's.

Should this guy see someone? Is he a sex addict without the sex, and suffering from a serious case of anxiety and selfishness?
