Tatts get my cock hard. I want to get a tattoo to cover an ugly birthmark on the middle of my back. It's about the size of two or three quarters. I want tattoo across the top of my back just because the idea gets my dick hard. I want to get a tattoo on both ass cheeks. Please leave your suggestions about what tattoos I should get here. Thanks. Also is it normal to see japanese characters written horizontally? Because in japan they write down the page not across.
