Threesome with gf, how risky for relationship?

[B_prettyswinggirl]

Does the girlfriend tend to be "pleasently surprised about the experience of the threesome or because of the other guy? Does the woman or the guy usually end the relationship from what you have seen?

It all depends on how good at communication you guys really are. If you're doing this with an open mind and talk talk talk about all aspects of what you both want out of the evening, then possibly you'll be ok.

I'd start with just arranging a sensual massage at a hotel near you and for the first night, not taking it any further than that. Then talk about the experience with your gf after and see how you both feel. There's no reason to take it faster than that if you want to keep the current relationship you have. Most under 30's that try this, do end up breaking up. If you sincerely think you want to go ahead with it, I recommend you go very very slowly.
