One of the guilty pleasures of this summers hit reality shows. Meet Dominic Briones, one of last season’s houseguests from Big Brother 13. Dominic is a cute 25 year old model from San Mateo, Ca.  Briones boyish good looks earned him the nickname P.Y.T. (Pretty Young Thing).  He’s 25, Filipino-Italian and still a virgin who is waiting for marriage, but also still lives at home.
