You don't-

Uh, getting laid is another way to say 'having sex'. And you don't say 'give someone sex' you have sex with them. Saying it that way makes it sound like they should pay you, which is totally OK but

An orgy is sex with lots of people. It can be a lot of fun.

But, seriously you're way too young to be thinking about getting it on with someone having sex. You should wait till you're older to think about learning how to do it.

Wait- is your friend going to have sex with someone? Tell me he's older than you please!
