What an enormous jerk to do this to you. Tell him that if he wants two girls so badly he needs to find two new ones...

He sounds ridiculous! He actually sounds like a child who has been deprived a toy. Honestly! He has no right (not does anyone, for that matter) to guilt you into doing something you're clearly uncomfortably with, especially regarding sex. You deserve to be treated with more respect! I'd kick his butt. xxx..

Jeez, I always wanted..a threesome too, but i wouldn't leave my girl to have one. What Ive found is that some fantasies should remain fantasies. Dump him. Do NOT pass 'go, do NOT collect $200...

Ewww, are you being serious?..Why would you even consider staying with this loser?..He's basically telling you he wants to sleep with someone else (or he wants you to) while the other person in the relationship is present...
..
Now, I have nothing against threesomes (I think they're kind of hot), but only if both people are into it...Your boyfriend is being a sexual bully, and you should break up with him immediately...Find a guy who respects your boundaries, and is happy just being with you....

I know a girl who told me that her boyfriend said he needed her to have regular threesomes. He wanted them at least once a week. He said he would do it once a month. She freaked out and said that no one should pressure you to do something you don't want to do sexually. ..

If you want to do it -- go for it. But if he's going to dump you because you won't let him f**k other women when you're in bed with him. Let him...

Dump his ass. If he uses the "you don't love me if you dont do this" argument, hes a greedy spoiled bastard. And if its over somethings sexual, then he's a douche...

Whatever you do, don't do anything without being sure you want to do it...
