This place allows us all somewhere to be someone other than ourselves. Someone we wish we could be, or would like to try to be. That's part of the fun. People like us (and I say us meaning you and I, and several of the others)...we've used our imaginations our entire lives to escape. Admittedly a lot of us have a few more years doing it than you do, but believe me when I say we get it. We don't any of us have the same problems, and I can't say I understand yours, but we all have similar results coming from different issues in our lives.
We're most of us outcasts irl. And we always have been. For me, I've been fat my entire life. I still weigh 350 lbs now. Admittedly I don't look it, but nevertheless it's true, and it's obvious that I'm obese, if not morbidly so. People have been cruel to me my entire life for it, especially in middle school. A fantasy world allows me to be someone or something else. An escape from my reality. I can do things here I'd never dare do irl.
I can be in a bedroom with another person, but it's difficult for me to 'perform.' I basically have to take care of myself and pretend they're not there, and then they can 'finish me off' if I get myself close. But it's a handicap...not to mention my meager endowment. (Probably another thing that negatively impacts my self-image.)
Stuttering doesn't mean you're a 'moron.' I can tell from your writing that you're not. I, myself, am a bit slow-witted. I have a hard time coming up with the words I want to say quickly, but having the time to think and compose my words properly helps. And I know I'm not a moron, I scored a 30 on my ACT. Graduated highschool with a cumulative 3.7 GPA. I'm just not snappy. I like to think things through before speaking.
And everyone's ugly in their own way. It's just that somewhere along the line, whether it was genetics or just some random people, it got decided that one version of ugly was more desirable. Substance is what really counts, and that's another reason we like the internet. People get to know our true selves before they get to see us and make preformed judgements.
As for me, I pathologically fear rejection, so I just never put myself out there. Someone has to make the effort with me, and I immediately give them my "laundry-list" of the things I find unattractive about myself, so that they can reject me right away or accept all of those things about me in spite of it all. We're all damaged in some way. And this time I don't mean just us, I mean the entire human race.
