What's the right way to ask a girl for a hookup/fwb?

Be honest! Say hey I'm not looking for anything serious. I think you're cool and beautiful and would love to be friends with benefits if you're interested, if not no worries I won't bug you again.

You'd be surprised how many girls don't mind. It's all about you ask and treat them. You should treat her with the same respect as any woman and have fun! Pleasure her and she'll do the same.

I always approached things honestly and only pursued guys who were the same.

A friend of mine claims he had a 10% success rate with "Let's phuque". Probably not the "right way", but it worked at least as well as my well orchestrated meetings with conversation, coffee, and casual dates.
