When you're not gay, but are sexually attracted to a single male.
Originated when a straight man fell for the luscious cheeks of a gay boy named Timmy, despite his sexuality having always been straight, and has continued to be nothing but straight, besides the one with the luscious cheeks.
Timmy : illsuck your dick
Straight man : God damnit im straight but I just cant resist that fat ass, I must be timmysexual
A sexual orientation that exists outside of Gender norms. A Tiddysexual is only attracted to big ass tiddies. They find Penises, Vaginas and Buttholes disgusting and repulsive. Also non of that Loli shit.
