For me, eyebrow piercing and nose piercings scream "girl" to me, but it's mainly girls I see with those piercings. When I see snake bites I just think of "punks" because I've seen them on guys and girls. Lip rings I see as more masculine, though, probably because I've seen more guys with them.
I think if you have the piercing in the wrong spot then it could draw notice to the more female aspects of your face, just like various bits of make-up can also.
