I've been best friends with my girlfriend for 15 years and I wonder what it would be like to have sex together. Will it hurt or help are relationship?

Whose relationship? Your relationship with her or the man with whom you exchanged marital vows?

If your best friend has no feelings like this it will ruin that relationship, as for as your marriage, it rill ruin that for sure.

Well, there are 3 or 4 people involved here. Not only you and your girlfriend.
How about everyone's feelings?

Next to that : is it out of curiosity, or do you have "special" feelings towards other women?
Does your girlfriend know that you have such feelings, and if so : what is her reaction to that?

Look before you leap!!

You don't have to act on every impulse! :) What a messed up life we would have if we did.

A husband is a wonderful thing to have; a best friend is a super thing to have in our lives.

The downside of you acting on an impulse is horrendous. :)

I'd say let it go... few fantasies ever live up to what you have dreamed up.


Far more to loose here that you have to gain. Unless Hubby has been asking for a 3 some.

I'd get the husbands perspective on bi curiosity first. Then I'd get your gf's veiws on lesbianism/bicuriosity, then I'd weigh up which relationship I'm not worried about losing, and then finally deciding to NOT act on this fantasy. I think that this will just go very bad all round.
