I'm 23 years old, I have 3 friends, and am socially dysfunctional. How uncommon is this behavior?

I'm in my late 20's and would say that I can relate. I suppose my situation may be even worse. I only really have 1 friend & don't fit in at work. It has been going on my whole life. I also am still a virgin. It doesn't bother me though because that is not a problem for me. But, it does bother me that I can't connect with people. But, when you really think about it, a lot of those "friendships" and "relationships" you see out there are superficial anyways.
