Everybody has their own reason for wanting whatever they have pierced pierced. That being said, some guys like having a girl who has her tongue pierced for an undisclosed reason, other guys don't like having a girl having her tongue pierced, and visa verse for girls liking guys having their tongue pierced for an undisclosed reason, and some don't. I personally would prefer a girl with a tongue ring, and I don't have my tongue pierced, never will anyways, don't feel like chipping teeth.
