My boyfriend wants a threesone..

of all the threesomes I have been lucky enough to have been involved, by far the MMF ones are hotter than the MFF, the novelty of the MFF soon wheres off, however seeing the F use and abuse 2 cocks never gets boring!

Well first of all you need to learn that "he wants to have another woman WITH me" does NOT mean he no longer finds you attractive.

Sometimes men want to experiment. And remember, he might also want to see YOU enjoy the other woman too.

So what do you do? You decide if you want this or not. If you do, then fine... if you don't then just say "no" and drop it. Don't make it into a big dramarama.

Remember - he trusted you enough to reveal one of his secret fantasies. If you punish him for that, it tells him he can't trust you with his real self.

I have to agree that many men do have this fantasy. Quite often, couples share fantasies during intimacy. Quite often, some couples don't share fantasies at all.

I wonder how many men in a committed relationship would actually go through with it.

Sharing such personal desires can be dangerous as it leaves one open to ridicule and could offend or even hurt the feelings of the other (as it seems it has done here).

You need to ask him the very question you have put forth. It could be that you are enough for him, and he was sharing a very common desire. It could also mean that he is a selfish, insensitive pig who places his own sexual gratification above your feelings.

All guys want a threesome. Well, most. They enjoy the thought of it, although some may not be willing to go through with the actual act of it. The only way you could compete with that is if you had two vaginas, so in that sense you are not enough.
