A
guy who is only kept around for sexual purposes, with no serious
romantic or emotional connection. Unlike a friend with benefits, a penisfriend's only function is to respond to bootycalls--an actual friendship does not not exist (but
one may develop as a side effect).
A dildo with its own life.
My roommate's trying to take it
slow with this new
guy she really likes, so she's
got a penisfriend on the side to vent all of her sexual frustration.
