It's not a dealbreaker...just blind the bastard, then he won't have to worry about my body going to shit, in fact, he'd better hope I don't castrate him. Other than that...not a dealbreaker!
He/she is hot looking, loves all your kinks, willing to be the 'perv' of your dreams...but...he/she hates all of your friends and hates it when you hang out with them and gives you the 'them or me' speech...dealbreaker, or no?
