Like Tish said, you are a little vague.
Is it right or wrong? That is TOTALLY a behind closed doors issue. And absolutely personal. I've read of women that are totally into them and find it quite arousing and enjoyable. And women that have tried it once, some say it was worth the experience, some not, some glad they tried it, some wish they hadn't. Either way, it is still a private matter that only you have to deal with.
And since you didn't say whether it would be with just any two guys or one of them you would be in some relationship with like a steady bf or dh. And who's idea is it, yours or one of the guys? There can be issues if one of them is a permenant partner. After the fact jealousy. A guy even a bf or dh would coax you into it, then afterwards not be able to handle having watched you enjoy the sex with the other guy a little two much. Of if a bf or dh was suggesting it, you have to wonder WHY he would want you to have sex with another guy to begin with.
Also if it would be just any two guys and one of them wasn't a very safe close friend, that would scare me. One guy when the testosterone takes over for the brain is hard enough to handle, let alone two guys. I'd be terrified of getting taken advantage of or ravaged against my wishes if things got out of hand.
But, if it's your idea and have a strong urge to find out and the guys are safe and you know they are safe and there won't be any permenant relationship issues afterwards then it is totally your business whether you do it or not.
Or if it has already happened and you're after support or affirmation, you should have said that. If that is the case, then if it's over it's over and move on and don't worry about it.
