How about you say something like: Now excuse me while I "insert blah blah here". So that they arn't waiting for you to say something. Or just smile or whatever to ease up the tension. That's what i'd do.

Now the first one's a little hard to do when you're in class. I realize that some of the time it's good and creating sexual tension. But when it's a guy who is staring at you I damn sure don't want that tension. I just want to know what going on in there head. Like I have had this situation before where they would just stare for like 5 seconds after a conversation, until I would look away and they would keep staring and finally look away. This is mainly a problem with women. Is it basically a mental shit test to see how I will react?[/b]

Yeah I am not necessarily worried about the guy part I just think it's creepy on their part. But you said you frame it for women as "I know you want me". You frame it that way or you actually say that? lol I always just assume it's because they think I'm attractive but wtf should I do if I have no more to say? just eye fuck the hell outta them? Like I said, It's starts to feel awkward and I'll blush and I know they see this.

Just go up to them and say "you can't look at me like that and not say anything"

I don't say I know they want me, my body flirts for me.

Boom. Sexual attraction. Try it, you will get an aha moment.

I remember K posted about this a long while ago. Im paraphrasing here:

If you find yourself running out of things to say or things get awkward then you could benefit from taking creative writing courses and participating in association games, giving you a richer pool from which to draw good conversation from.

Ive had that once or twice, i normally laugh and say she is boring, and then point out how everone els is talking so well, and we have nothing to say to each other, and its because everyone els has hired writer that behind the scene are giving them interesting things to talk about and that were cheap for not providing each other with professional conversation. Then we normally go into a take the piss out of "james bond esc" one liners, mocking other people, bringing her into our own little world more, and giving our conversation endless possibility as we are making shit up

You can always eject yourself out of the conversation or dive into another one that other people are in.

For me, I don't always feel like talking so when this happens, I usually just give her a little shrug kind of look. Sometimes she responds back with a similar look, other times she just looks away
