Another male viewpoint : Two women together, even only watching, is one of the most intensly erotic things I (and I suspect many men) can experiance - being asked to take part is a exiting added bonus. I have had one threesome, and it is something that can never be beaten or fogotten. Speaking for myself, it could never, ever detract from my partner - how lucky could one be to find a partner willing to allow you to share a girl!!! If anything it would make her all the more desirable. My current partner would never enterain the idea of another women (shock, horror!) - which is sad for both of us. (I would be far more likely to leave her for somebody who IS bi curious!!). Enjoy - and if your relationship suffers because of your wonderful interest - he was insane and your probably well rid!
