Please help

Guys please no hate cause I see a lot of that sometimes on these kinda groups... I have never dealt with this before with my leopard gecko... I was helping get some shed off his tail tonight and noticed his private area looks like this... Idk if it's shed that's stuck or poop or what it is ... Can someone please walk me through what to do to help my little guy..... These are the best pics I could get I'm sorry they're kinda crappy he was moving around a bit ...
