Penis Tattoo

I want a tattoo just above my cock or on it, I was thinking something tribal.

Looking for suggestions or advice from anyone who has had one done already
I toyed with the idea many times over the years but never gone through with it, I know one dude who has an elephants head around his dick with his dick as the trunk. Kind of comical and a talking point but it looks shit really, I know he regrets it.
 
I'd recommend getting a 50 pound note or a U.S. $100 bill tattooed on your dick.

Women can' resist blowing a $100 in the U.S. Might work in GB.

Bad idea. Inflation can be a bitch with that sort of thing.

What if it's a younger guy and 10-15 years (months) from now a hundred with Big Ben isn't worth five bucks in today's money?
