One who loves sex so much, they are a glutton.
Jill is a total sex pig. She has an insatiable sexual appetite.

A SexPig is a gay guy who can't get enough dirty sex. Alone, in groups, one-on-one, safe or bareback - it doesn't matter. The more the merrier, although most pigs prefer BB. Some pigs like to wear gear like leather, rubber, denium. Some SexPigs have a favorite sextoy - a 12-inch dildo or a superlarge buttplug. But they all have one thing in common: they just can't get enough mansex.
See that guy over there he's such a dirty little sex pig, he'll squeal for any guy.
