I am currently in high school and I am a sophomore. I had a crush on this guy I took class with last year. I was to shy to talk to him last year, but this year I have another class with him. I got paired into a group of four with him. He is always making this sexual acts toward me with hands or mouth. I know he's sounding kind of raunchy at this point, but I still found him attractive. He let me befriend him on face book and I made the first mistake by telling him I have a crush on him.

I recently found out he has a girlfriend taking a class right above our classroom. I have seen him walking up behind this girl and wrapping his arms around her waist. He keeps looking at me every time he nibbles on her neck. There are only two guys sitting next to me during that time. I know that's not his girlfriend because his current is always posting pictures of each other making out. He has started turning in my direction and puts this ruler between his crotch, and begins to tap on my book while I am studying the material. He desk is less than a foot away from mine and I have tried to ignore now.

Your title is 'do I deserve better.'
I would hope so. Only you can decide what you want to put up with. It boggles my mind that you even THINK about this guy. He's a player. Are you? If not, ignore him.
If you mean by asking if you deserve better that HE is supposed to be a different person for your sake, that makes no sense. None of us gets to define what someone else is supposed to be.
It seems pretty clear that he is enjoying and taking advantage of your crush for all it's worth. It was a mistake to ask to be his friend on Facebook AND admit to a crush. Drop the whole thing and take relationships more slowly next time.

He likes the attention, if he became your boyfriend you would be in the same position his current girlfriend is in. Only difference is maybe you might watch out for him making raunchy acts toward the next girl he decides to give attention to. Don't be played

You are going to get the same answers from the same people by asking the same question twice. We need you to be replying to the first one you started.

He's a jerk, plain and simple. Why even deal with him anymore?

Drop him on FB and ignore him otherwise.

This guy is a jerk and your being his friend on Facebook, telling him you have a crush on him and putting up with his rude behavior make you seem either desperate or as raunchy as he his.
He has a girl friend and he's a jerk. Unfriend him and leave him alone.
