Look if the guy giving you the tattoo comments I wouldn't walk out. I'm pretty much the exact same size as you and I say go for it. It's for you it's personal and who gives a ****.
I have stretch marks there and fat and honestly I would get one there too it's private easy to hide and not for full show. If you want it go for it I'm sure it will look great! Good luck!
I'm also 5'7" and about 160 pounds. When I got a tattoo across my lower stomach, the tattoo artist did give me advice to get it as low as possible in case I ever got pregnant. Don't be ashamed to ask for placement help and don't be offended if the tattoo artist gives advice - they've most likely been doing it for years and have seen how tattoos age in certain places on the body.
But if the "advice" comes off rude, don't be afraid to walk out and find another tattoo artist. Don't for one second think that you have to put up with that ****.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
