Why?

I don’t know your specifics, man, but I can tell you that it usually gets better. Don’t buy into this whole “I need to get laid at by a certain age or I’m a loser,” hype. First off, you’d be amazed at how many people, even traditionally attractive people, do NOT lose their virginity until later in life. I was only a year older than you before I had sex for the first time, and honestly all I could think of was how over-rated the whole act is in and of itself. I’m one of those weird guys who can’t enjoy casual meaningless sex, and I suspect you may be the same way.

I didn’t have a REAL relationship until I was in my mid-20’s. And even then, you have to be careful of crazy chicks. There are just as many of them as there are asshole guys, and these people can leave you so emotionally drained that you’ll end up regretting getting into a relationship just for the hell of it.

Your Aspergers is something that you’re going to have to learn to manage in order to function is social situations, but if you’re reasonably intelligent and open to suggestions and counseling, this is entirely achievable. I know how this condition can make it difficult to associate and connect with others, since I suffer form a mild form of it myself, and also had to endure bullying in my younger years, which of course caused depression as well. But after years of experience and learning how to interact, read social cues, and modify my behavior, social situations not only became easier but even enjoyable, and making friends becomes second nature. Some people have this ability naturally, and some people need to learn it like a skill. guys like you and me fall into the later category, but you can become successful at it.

I suspect that your low opinion of your physical appearance may simply be psychological, caused by low self-esteem, unrealistic expectations, and too much exposure to idealized media body images that don’t reflect what the average real person looks like. I don’t know what you look like personally, but I do know that even HIDEOUS looking people manage to get laid. Personality goes a lot further than you may expect, and self-confidence is attractive to everybody.

I know it’s hard right now, but you have to believe that things will get better if you make the appropriate mental and behavioral adjustments. Don’t give up this early and life just because you’re having some difficulty attracting girls right now. You can fix that, trust me.
