>>20655408Skin is different,for different parts of the body; to that end,your skin on your lips are different to the skin on the head of your cock.Likewise,the skin around your anus is different to the skin which constitutes your
asshole.To that end,the skin around the general area of a girls asshole is different,but,like all humans,everything is similar,but within different parameters.
Saying that,skin discoloration as per your image is,and can be caused by the friction of two skin surfaces rubbing together.
Either way,pussy is pussy,asshole is asshole;-)
It’s all fair game,to a real dude;-)
