You have very good communications skills with you SO ..

But if you want to try a new thing I would say do it with some she would feel comfortable with ...

That is there for Safe sex ...

If she is willing to do that then I think its all right

Sounds to me she is getting left out of your thought because you want to try sex with a man..

I would ask her to find the man for you and have a threesome so she won't feel left out at all ...

A good suggestion is try to find a gay man that wants to try to have sex with a woman .. That way there won't be any hurt feelings or mix ups on what is right or wrong and your So won't feel as jealous as she does now if she is thinking that you want a straight man to try with..

Just my thoughts but good luck !
