Where do guys find tattoos sexy?
im 17 and was thinking of getting a tattoo on my side where my jeans start (thats where i think it looks sexy but id like ur opinion too) but then would that stretch and distort over time if i gain/lose weight?
where else would be sexy?

DO NOT get a tattoo because it looks "sexy"
That will be the most idiotic thing you could do.
Get something that means something to you.
&& The middle of your back (NOT tramp-stamp) is the best.
It's easy to cover.
