Stand up at an angle where there is a clear shot of his groin area and "accidentally" drop your pencil or book on his lap then quickly (act like it is just a reflex) put your hand near that area to pick up your pencil/book and give a nice smile. OR you can ask to borrow a pencil and when he hands you his pencil, make sure to touch his hand softly. DON'T talk sexually! keep it somewhat classy.
@Anonymous Yeah, It would be cruel to do that to someone. If you know he has a crush on you, why not ask him out on a date? The other way is just mean and childish.
Sincerely,
Erotica
If you have a nice butt, wear yoga pants and "accidentally" bend over in front of him to grab something you dropped. If you have nice cleavage then wear a shirt that shows them off and slightly bend down so he can see.
Sit close to him, if you have shirt cleavage show it off, or any other cleavage.
Thanks!

Grow some ovaries.
Boob cleavage and mini skirt works for everyone ;) don't wear bra and he could realise that easily
The girl in my geometry class keeps trying new and more innovative ways to give me a boner for reasons I don't know why but we sit in the back of the class in kind of a blind spot when everyone stares at the board. She keeps flirting with me playing a game of footsie and licking her lips while having her mouth open staring at my crouch when I'm sitting down.
Stand close to him and talk to him in a cute way, smile, keep eye contact and caress his arm. Boom.
IF your not touching him, probably not possible, Unless your insanely hot and are practically naked...
Pretty much I could check out girls at the beach all day and not get hard.
same here, I read her list, and I don't see how its possible with out stroking it for him or at least butt ass naked, and a banging body..
So what you're saying is you want to tease him sexually but without following through on anything. Is that right?
We will be hanging out during the weekend. Things may happen.. And I'm curious. I've never seen a guy get a boner and I would prefer it to be in school so he doesn't try anything to fast.
do you guys see how she thinks about this? where do they get this?
Don't intentionally get him all sexually worked up if you are not going to follow through. If you plan to follow through on the weekend then wait until then. What you're talking about here is cruel and there are names for girls who do that sort of thing intentionally to guys.
