<human>: Can you condense the text into three sentences or less?

The first impression I got of my roommate was on facebook over the summer. He appeared to me to be overly sexual, mentioning how eager he was to "get some pussy". After meeting him he turned out to just be a average virgin freshman, which surprised me after the dialogue we had had previously. 

Now, during a brosesh, he admitted that he's never once masturbated till ejaculation. He's touched himself, but never finished. He says that he's wet the bed a lot, but I think it's more like he constantly had wet dreams. Also, he refuses to wear a shirt in the room, with hardly a justification for it ( I figure this has something to do with the whole 'pent-up-semen') thing.

My suitemates and I are wondering if the lack of jerking has had a significant effect on the development of his personality, especially the shame that would accompany later-age bedwetting. 
For his sake, we all encouraged him to jerk off, admitting how recently we all have done it and how amazing it is and all that jazz. Yet he still hasn't, and won't justify it with anything but complete avoidance of the topic. 

Ironically, despite all of the male bravado he displayed online, he quails before any opportunity to have sex with a girl, even when the opportunity was immediate and certain. I know the virginity plays a part, but the fact that he hasn't even touched himself, let alone be touched by a girl, is going to be an immense barrier to sexual progression.

Should we continue to encourage his jerking (without like 'rape-forcing' it to happen)?
Will there be a substantial change to his personality at his age for it happening?
What kind of situation in his past is preventing him from desiring to touch himself like the majority of people?
<bot>: My roommate has never ejaculated aside from wetdreams, and is avoiding jerking off now. Why? And will jerking affect him now?
