“looking for a woman to play out the guy’s MFF fantasy”

Sometimes the driving force is a bi-curious woman. What usually happens is that the boyfriend agrees to it because he sees a MDF threesome as being hot, and sapphic love as being less real or serious. Then he freaks out during/after the hookup because of insecurity he feels when seeing his girlfriend enthusiastically making out with a woman. I’ve learned the unpleasant way that it’s no fun to be unicorn hunted.

The worst part is when they try to hide what they’re doing. I once only found out a woman had a boyfriend and that they were looking for a MFF threesome on the third date. Trying to hide their intentions is gross because it shows they have some awareness of how people don’t like being instrumentalised in this way.
