I say girl from my looking at her in person. Ill get some better pics tomorrow.
Update it's in the trees so cant get a good shot. I was reading your post from a while ago and It looks like a straight line to the vent compared to an indent before. Still not sure myself so Ill get a better picture later for opinions.
I know you wanted a male but trust me, you will end up liking her just as much. When I kept panthers I actually liked my females the best. They have a funny demeanor like all female species...............or might I say gluttons They also have some nice coloration.
