Seems to me if you wanted to have a threesome, you wouldn't want to risk complications by having the third party romantically interested.
Unless you're one of those polygamous dudes that wants a harem to fawn over you. I'd call that douchebaggery, but I think it'd be pretty awesome to have a bunch of husbands, so who am I to judge
Anyway if you start saying OH MAN THIS GIRL THINKS I AM CREEPY WHAT DO I DO I think you could talk to her and explain how the folks on the internet thought it was a hilarious misunderstanding
