The thought of getting penis tattooed has crossed my mind too...I think it'll be really painful but then, as it'll be a small piece (haha, well looking at mine, its not
that large

) it would be short and sweet!
I think your red stripes would look really cool. And I think to keep an erection throughout you prob need some medicine/pills for that? I mean, maybe the pain might keep it erect though?
How do you think it'll look when its not erect?
