Male or female?

My beardie, Thunder, seems to be a female to me, but his previous owners said he was a male ;-; Could anybody help me make sure of his/her sex? (Tried the flashlight thing, that didn't work)

We need a view from behind, after the vent

Female. After the vents on males they'll have two lumps, one on each side of the tail, on females it's a single lump in the middle of the tail right after the vent
