In a low cut suit some is inevitable but this crease is more my tailbone than butt crack.
The virgin skin burned so fast lol I had to put cream on there at night.
As far as at the pool or beach and having pubes and ass crack out, depends on the place.
I wouldn't say it looked super gross or pedo.
Also, swimmers sometimes deliberately wear suits a size down for competition.
Members like posting their speedo selfies so I don't like that to be 100% public.
