Girls, My girlfriend wants to have a Threesome with her EX! Should I?

Question

So my girlfriend and I have a great sex life. We've had a threesome with a woman in the past, while on vacation, which was awesome. She recently revealed that she would like to have a threesome with a guy next time, including guy/guy action as well. We discussed it and while I am hesitant, I realize it is fair since she was hesitant to be with a woman at first but did it for me and ended up loving the experience. We have just been unsure how to make it happen. We are both hesitant to meet some random guy at a bar or online for this. 
So.. she bumped into one of her exes the other day at the coffee shop. He's planning to take a job across country in a month so she thinks he might be an option! It won't get awkward after because realistically, we'd never see him again. 

She obviously didn't ask him without talking to me but thinks he would totally do it. He'd be wary of the guy/guy action unless he could be the "top" though which is fine with me because this is for her benefit and that is what she wants to see. 
She says he was great in bed and has a great body and penis but nothing really in common. There was no relationship potential beyond that and this was reinforced during their brief reaquaintance at the coffee shop. He is not a "bad" guy or a jerk, they just weren't compatible in the end. 

I asked her if, I were willing to approve, would she like to just have sex with her ex while I watch or perhaps, I'm not even there.. She very quickly and decisively said NO. She is turned on by two guys pleasing her at once, turned on by seeing some guy/guy action and turned on by having two people who mean (t) a lot to her in very differenty ways, making love to her at once. 

In a way it's also about sharing..
When we were on vacation, we met this amazing, sexy young woman that we both shared together and she wants to share this guy who has a great body and is great in bed and whom she trusts

Here's how I feel. Yes it's only fair! The fact that your open to it for her sexual pleasure prove's your in a comfortable place with her sexually.

I've been in MFM threesomes before and I believe you should only do it with a guy your girlfriend feels comfortable with, knows more about and you can also feel comfortable around. You need to check all insecurities at the door with this. Also you two should meet with him outside of the bedroom before.

Can you find yourself getting involved in some action with him? Just go for it and try lose any hangups. With a MFM it's bound to happen anyway. I think it's hot, and I'm not the only girl who does. You'd both be naked and inevitably touch each other.

I disagree that it would wreck your relationship. Obviously when you had a threesome with another girl it didn't. So I don't see how it would with another guy. You stated that he's not a bad guy or a "jerk" with the two of them uninterested in a relationship.

Honestly the way you describe him, it sounds like he's the perfect guy for you two. Someone she trusts, is someone you can, especially in the context of threesomes.

me and my boyfriend had a similar questioning about his ex-girlfriend. she is married, but she was missing group sex. It took a while but we did it and we still do quite often.
I enjoy it a lot, she is very sportive and dynamic while I am more a feline style.
There had been no problem at all in our relationship.

If you get to have one with a woman, so then let her have one with a man. Fair is fair, right? And did she get to approve when you had the threesome with the girl? Why is it only up to you?

Don't do it, it will wreck your relationship. While I wouldn't have a threesome with my boyfriend and someone else, I don't think exes should be involved, doing it with a stranger is one thing, but feelings could reemerge and someone could get hurt e. g you!

Well you already did it with another girl...

I think it sounds logical since you already did it with another girl. As long as you're sure you can trust her that she doesn't have any love feelings for him any more.
