@shrekssister You are most definitely not in the minority! I'd say the majority of people aren't swingers...
I've been in the lifestyle (and it is a lifestyle choice, not simply for people to get their rocks off, although you do get them...) for a few years, and I can't imagine going back to a "normal" relationship now that I've had a peek damn good look behind the curtain.
It's not for everyone, but if you go in with an open mind, there are lots of really nice people to meet. Along with some not-so-nice, so choose carefully. As a (I assume) single female, you will be spolit for choice.
Just remember that you should never be put in a posiiton where sex is expected - no is always an acceptable answer.
@Thisismysexforumname go for it! Treat it as a night out, with no expectations (see above), and if all you do is have sex together in a more public place, then that's all good!
Life is far too short to wonder what if!
Happy to give more information if required - just ask!
