Stay away from him, masturbate, and get on with your life.

use him and throw him away like you would a cucumber

While not nescessary common, I'd say it's normal. This might come off as a sexist remark, but my personal experience is girls have a harder time of seperating sex and emotions. If you can make that seperation, then go ahead and just have physical sex with him, if you want. Just don't get emotionally attached, because as you've said, he'll just use you.

Shove a banana in your mouth, cunt and ass. Then do a dance. Then shoot yourself in the face, the world will then be a better place.

Guys will use you, if you let them. AND he certainly is if he's grabbing you.

It's normal to have feelings for him, but that doesn't mean it's a good idea to get involved with him.

You said he's really isn't a good person at all, and that you think he's hot. Are you attracted to bad boys?. I think if he just grabs you like that, that he's very immature, you shouldn't stand for it. Certainly the very LAST thing you want to be doing is to be concidering having sex with him. I mean can you just imagine if he makes you pregnant?. If he feels he can use you, then he will certainly try. If he's the kind of person who uses people and senses that you're desperate for him, he'll manipulate you into moving in with him, drag you down with mind games, say to you that you're ugly and useless, maybe beat you too. Some guys are like this, and tend to be very weak and needy deep down, and this is their way, so they think, that they'll be able to keep you with them. By dragging you so low that you'll think no other man would be interested in you. He'll also be quite content to see you clearing up after him wherever he goes around the house. Not a very nice life at all. You may think I'm going over the top with my next comment, but fact is women's prisons/jails are full of girls that got with a man like this and ended up so messed up they lost it one split second and killed him!. Next time you see him, disagree with what he says....mock him!!!!, but look him in the eye at the same time. because if he is this kind of monster, you'll certainly see a glint of rage in his eye. He probably won't do nothing now as he's desperate to get you into bed, so until you do you still have the upper hand over him. But take note of that momentary angry glint in his eye, because if he "does" get his way with you, then you'll see a lot more of this, for the most trivial reasons imaginable, only now followed by a torrent of abuse and his fist.
If you do give in to him just the "once", the second time will come more easy, then the third, by then he's got you where he want's.
In short, he's a parasite. OK! I don't know you or this guy, but if you're having doubts about him, and you clearly are to write about it here, then for goodness sake tell him where to shove his wandering hands and go find someone with a bit more respect for women, who you also find that's hot. Anyway hun' bet you're waaay hotter than him ;) Hey! take care yeah!.

He is a wanker.

Sure you can fuck him and be done with it but what are you going to get out of it apart from a shag.. he might be crap anyway.

Oh! bye the way, yes it's normal to feel this way about this guy. That'll be because he probably seems confident, assertive, and in control, much like the typical alpha male which women Naturally find attractive. Only this guy is no alpha male but just an immature weed with a big ego. Like the other guy says: "He'll probably be crap anyway". Well if he's that immature with Women, "just grabbing you" then you can guarantee he is crap!.
