I admire married couples who enter into the blissful world of Swinging. I think it should be hard to convince the wife more than hubby to embrace the 'sexual swap life' and to finally get her to accept it. But at the end, the rewards must be great!
I like to hear from experienced swingers in relationships as to how they were introduced into the world of swinging, how both hubby and wife came to accept it and what they feel about this lifestyle.
We actually talked about our sexual fantasies before we got together and once we were comfortable in our relationship those fantasies were explored, due to 3sums being hard to find than couples we ended up testing the waters there and then found we preferred them over 3sums.
I think the only successful way to bring it into an already established relationship is open communication and an open mind... but most of all going in with the respect to close the topic if required.
