Probably the OP has a faulty thinking, and he doesn't seem easy to deal with from his posts, but there is a fact which is that guys are expected to be funny and confident and outgoing in the most part, and there is emphasis on that. Just read the profile of many (especially young) women on any dating site. These qualities are almost always present. In this respect, I don't think the OP is way off.

Maybe the OP needs to accept himself, but at the same time he needs to show that he's interesting in a comfortable way. I've accepted myself, but I don't know how to communicate with others in acceptable ways, and the result is I'm alone, and I've been for many years, although being shy and socially awkward isn't the only reason in my case.

Good luck to the OP listening to these advises. Just consider that probably most of the women commented here (and interestingly, most posts, as it's always the case in this board, are from women!!) are not as young as the girls you are looking for, and probably they view things differently because of maturity and experience.
