Depends on the guy on some it looks OK if it's small but I find it unatractive what's the point in having people see through your ears it gives me the shivers I never do it cause I love earrings thank you very much lol on girls it looks horrible one of my friend has it and I don't like how it looks all in all it depends in the person some look fine if it's small :) I like piercings on guys and tattoos :)
I think gauges are weird. I like body mod, but I don't see the point in stretching a hole in your skin. I wouldn't call it a turn off, but it freaks me out a little. It would only be a turn off for me if the hole was HUGE.
Its a major turn off for me and I think its repulsive and nasty. That is my own personal opinion about it. I am sure there are lots of people that say the same thing about tattoos or my face since I have vitiligo and tattoos.
