<human>: I am a senior in college, as is my friend. We met freshman year in the dorms when I saw he was always alone and then befriended him. He is autistic, most likely Asperger's. I was his first ever friend.

I don't know how else to say it, and it might sound mean, but he is pretty autistic. He is the nicest guy you'd ever meet and tries so hard with people, but he really isn't great at socializing. He KNOWS a lot of people, but me and my friend are his only actual friends who took the time to get to know him. A lot of people are turned off by certain traits he has, which is understandable. Most notably, he has some extreme fears, extreme clinginess, can be bothersome, apologizes excessively, doesn't initiate things, etc. Ultimately just has a hard time reading social cues, which I understand is a part of autism.

It's just sad to me. No one really takes the time to get to know him. He's a great guy. But at the same time, I see why people do, because he can get very overwhelming, even with me. Like earlier this year, he was getting very clingy with me and I had to tell him to tone it down a bit, which he still has trouble doing. But me and my friend will be graduating and without us, this guy has no friends or life. 

Simply put, there are certain things he does that constantly turn people off. Besides me and my friend, he has no friends, but he always appreciates our blunt honesty with him. Should I really try to teach him to socialize? It feels wrong, and I feel terrible writing this, but he does ask me for social advice all the time and I do help him out when he asks.

Can you condense the text into a few key points?
<bot>: My autistic friend truly does not know how to socialize and has many traits that turn people off. Is it wrong to "train" him how to socialize correctly? How do I do it?
