Actually you do. Price jumps for tattooing that is. Its kinda like this, people don't want to touch your junk, so if they are gonna do it they are gonna get paid to do it. I'm a guy, so messing around a gals crotch doesn't bother me in the slightest, but I'm still messing around a gal's crotch and I'm doing it professionally, not sexually. I do tattooing and piercing and as a pro I've learned that every person is a canvas. When I sit down to work, that is it, they are a canvas, but it is still uncomfortable working in certain areas. I'll do it, but it costs more.
Now with guys its different. Call me what you want but I don't want anything to do with a guys junk. Period. I've told my wife that if she wants to do genital piercings on guys she's free to do them, but I won't. So far she has refused, simply because she isn't comfortable doing it. Some people don't care and will do either, or, but I'm not one of them.
In the penis there is a major vein and if you pierce wrong your not gonna be happy, in women there is a chance of permanant sensation loss if done wrong. I think I'd pay more to insure it was done right, by someone comfortable with doing it.
If you're so cool, where's your tattoo???
