sexing savannahs

[Pirranha]

is there anyone who can sex savannahs easily and tell me what to look for?
i have one that im told is a male but i want to know for sure-ill try to attach a pic :

I'd say male, too. See those bulges on the underside of the base of his tail? That's where the hemipenes are stored (inverted). Females have similar organs, called hemiclitori, but they are usually smaller and therefore give a smaller bulge.

Yeah, its pretty touchy... I think mine is a female, since i've seen her hemiclitori everted and there was no fluff at the end like for the hemipenis...
