This is in my bucket list and I'm cool to start pursuing it now.

How does it work?
Do you just bring it up to a girl you're intimate with, plate, and see how she behaves?
I brought the subject to one and she jokingly assumed I'd be inviting a guy.
Do you have to lurk around the subject of her with other women before to get her to spill out some straw that you might come to grasp on later?
Do you just say fuck it and go to lgbt bars to look for women there?
