Well, I apologize for being so general. I do know that some people have social shyness and don't find making friends very easy. My experiences and experiences of others that I happen to know about indicate that if we are active and do things we enjoy we will meet people with similar interests, thus giving us things in common which makes it easier for relationships to develop. I hope you don't just stay at home and not be active and willing to get involved in things because of this. I have a sense that you are young but I don't know you at all. Best wishes for you, Mapofsteel.
Chin up, M. Asperger's isn't a death sentence. You may find yourself with one or two dear friends, which is a whole lot better than a large circle of fair-weather ones. Paul Dirac, a famous Asperger's sufferer, was arguably the greatest mathematical physicist of all time and was taciturn to the point of surliness. Had ONE close friend whom he met in middle age - he married her.
The implication of the question was that if he has too many female friends, he is unmasculine. If he prefers the company of men, he could be gay, which some people regard as less than masculine. What the hell do I know?
