This is not a contest. From what I have seen and the conclusion I can make from all of that; the picture shows a male. Sorry, I can't make a case to defend my point in English. I'm happy to be wrong tho.
@Harry Haller Because of the epigastric furrow. A male cannot have an epigastric furrow (gonoslit) with this wide of an opening - it's against their anatomy. Interestingly, individual animals can show some differences in exactly how the area looks, so you need to know which signs to look for and which to disregard.
