I was at a Halloween party tonight set up by the University but "sponsored" by one of the frats. This is the good frat on my campus. Honorable boys who even let gays join. Anyhoo, I was dancing with this guy I know (who isn't part of the frat) and even though it was a dry party, he was very obviously drunk. He reached out and grabbed both my boobs. I wasn't even dressed in anything even approximating slutty. This was my first time ever being full out grabbed by a guy, and I was so stunned that I just froze. He must have sensed my uneasiness because he let go, but he kept following me around. I finally got a hold of one of my friends and escaped the party.

I talked to my sister (who has had experience with this kind of thing) and she told me that what I should do next time is slap the guy and tell him I'm not that kind of girl. Is this the right thing to do with a drunk? What should I have done if he was sober? I feel so dirty and uneasy and I can't get the feeling to go away. I had trouble getting into my jammies and I get shivers whenever I brush against my boobs. What can I do to get the feeling to go away?

The guy was a jerk and deserves to be treated like a jerk. So give him a warning- LET GO NOW - and if he doesn't - a slap is definitely in order.

You have nothing to feel bad about. You did nothing wrong. Just put it out of your mind and remember that guys when they drink far too often use that as an excuse to behave badly. Don't buy it! A good guy is a good guy even when drunk.

These types of incidents destroy it for us good guys. Probably he will not remember what he did and you learned a good lesson.

You need to learn how to avoid a situation where this danger can lurk, and how to react if it does. Frat-type parties are known sources of drinking, drugs and sexual encounters of which you are now well aware. Just being there put you at some risk. Same with dimly lit streets, roads, buildings, dorms and parking lots. There is always some creep lurking around trying to peek at, touch or even rape a woman.
If these type situations are unavoidable,arm yourself with a can of mace for protection. A couple of lessons in self-defense might put you at ease. It's all about being aware of surroundings and being ready to react appropriately.In this instance, my guess is that a swift kick to the groin was called for.

Thanks everyone for all your wonderful advice. The guy who grabbed me actually came up to me after class and apologized. I accepted his apology, but you can be sure I'm going to be especially careful around him... praticularly when he's drunk.

I think it was decent and kind of him to apologize to you, however the following statement of yours below is somewhat troublesome.

You wrote, "I accepted his apology, but you can be sure I'm going to be especially careful around him... particularly when he's drunk."

I'm trying to guess why you would want to be around ANYBODY when they are drunk. You already know it's dangerous. I would think this is a person, however humble when sober, that you would want to avoid at all costs. This leads me to believe you think he is okay when he isn't....which in that case being around him at all could lead to trouble. Gregorio

I hadn't thought of it that way, but you make a good point.
