What do I do about an autistic man who has an obsession with me?

Anonymous
There's this guy at my college. I guess he spotted me from a distance and ever since then he's been kind of following me around campus.
I believe he is autistic, because I've studied psychology and I have also had autistic family members and he exhibits all the signs:
extremely awkward social behavior, obsessive behavior, poor conversational skills, and lack of boundaries.
Well he saw me for the first time a few days ago and today he came up to me randomly and gave me a hug!! out of nowhere. then said "okay bye" and walked away.
He followed me again later, and asked to walk around campus with me. well he asked me "You're 5 years older than me? what can i do to make myself look older? If I was older would you go out with me?"
and kept trying to touch me and give me hugs, I told him I wasn't comfortable with that and he apologized and said I just look "huggable"
He asked me if i want to sit on his leg and then he asked to pick me up and carry me?
Like.. I don't even know you.. what the hell?
He keeps asking me about my chest tattoo and wanting to see it.
I don't know, it's just very weird and I think I should report him.
But now I'm just curious... Does this sound like autism to you?
He kind of just says whatever's on his mind and he's very awkward...
And what happens in a person's mind to make them act so obsessive before they even
officially meet someone?

I am trying to be sensitive because I know he doesn't mean any harm so I don't want to hurt his feelings but he does make me uncomfortable sometimes. I just don't know how to approach it. There's no reason for me to be rude to him.
