The problem with nice guys vs. jerks is wishful thinking. Every man wants to think that he's a great guy, that he'll be great in bed, and that he would have no problem making someone happy.
It's arrogance, plain and simple. When a man's worldview crashes around him, instead of accepting that he might have to figure out what he's doing wrong, and make some actual changes, he starts spouting arrogance. That's when everyone starts whispering to their friends that you should be avoided, and rightly so.
I know that I'll have to make changes in my life for anything to work. I know that without changing, whoever I end up with will probably become miserable. That's the difference between real nice guys who can adapt, and the online ramblers who complain about not getting laid.
As sorry as I am to say this, a guy with Asperger's Syndrome is never going to be Hugh Hefner. You can get off to it as much as you want, but it'll never happen. You can either focus on finding a genuine relationship with reasonable expectations, or continue whining and expecting pity that you'll never receive.
You reap what you sow. Start planting something with good returns.
