Promise you won't be weird about it afterword?

From Nerve.com's "Sex Advice From..." series. This week it's "Sex Advice from DJs." This was my favorite question.
From DJ Sarah (24):

Q: What is the best technique to prevent premature ejaculation?

A: Girls should talk about their weight. That’ll make the boy be like, “Oh, man, this girl’s so annoying,” and it’ll stop him from thinking about how he’s going to come.

And this is pretty great too:

Q: How do you coax your friends into group sex?

A: Grab one of the people you want involved — let’s say it’s a girl. Point to the third party — let’s say it’s a boy. Say, “Check out that cute guy. Would you fuck him?” If she says yes, say, “Me too. Why don’t we totally fuck him together?” Then — and most importantly — say, "Promise you won't be weird about it afterward?" If she promises, you’re all set. Once you’ve got the girl signed on to the project, roping in the boy should be a piece of cake.
