I've read articles about men wanting to bring another partner, be it male or female, into the game. But as a woman, I'm not really sure how to bring this up with my boyfriend. It's more or less that I would like to bring someone else into our sexual relationship, for sex with both of us, but I'm not sure how to broach the topic or do this. So, I set about asking here. How should I ask? What should I even look into when considering another sexual partner?
