Sexually frustrated - want to give (random) guy a *******?

Quick Background:

alright, so I'm 20 and still a virgin. It's not from people TRUST me. I have had lots of guys trying to get in my pants but I don't want my first time to be for a random **** (though I feel it may come down to it).

Anyways i'm in my second year in University (wanting to be high-school math teacher). Anyways I just wanted to do something sexual. You know? I feel so very sexually frustrated and at some times I feel like I just need some guy to come and screw me senseless type of sexually frustrated. So because of which I have found some good porn sites to get me excited enough to ***. But now I feel like it is just not enough.

Cumming to my Question:

So I figured I would start out small and just go to one of the On-Res-Parties and find a guy to blow because I've always wanted to do that.

Question,

So my actual question now that you have some background information is,

how do I go about doing this?

I mean I think I've know how to suck a guy (watched enough porn). But how do I approach someone and target someone as the guy I know I want? I'm just very sexually frustrated and need some action but want to start off slower, than a quick 'just a ***' type of thing.

So if anyone has an answer or wishes to share some info that they wish they had before they engaged in sexual activity it would be greatly appreciated.

Thanks, and please no narrow-minded answers. This isn't a joke question.

ps. I already know about safe sex and having the guy have a condom and all that for sexual intercourse.
