Been dating this woman for few months she says she digs girls. How do I her to a couples session.
just come right out and say or ask if she'd like to try a 3some. But don't do that on a sunday morning while you're watching a church sermon on TV, buzzkill. Maybe if you're out at a bar where there are some hot looking chick babes would be a good time, that would be great timing.
I'd say just take your time....No need to rush things, it may backfire on you. If it happens it happens.
be patient...nothing more uncomfortable in a threesome situation if one person is "not really into it"
then when she is really ready---hang on and have fun!
