Quagmire, clearly
In the words of the LEGEND that is Peter Griffin (no not that one):
"A heartless sex hound"
'On one occasion, while out at sea with Peter and his friends, Quagmire confessed to a seemingly endless chain of bizarre sexual acts, ranging from picking up illegal aliens at Home Depot and Jo-Ann Fabrics stores to suffocate them while he masturbated to anally penetrating a spider monkey while reciting the Pledge of Allegiance.'
