Hi there....can you post a couple more pics, and twist the tail gently ? Sometimes that will reveal slight lumps under the skin above the vent. It looks female there, but some males show bulges later than others.
Oh will do. I got him about 2 months ago so I'm guessing she's only 3-4 months old. Not sure. I'll check again later down the road. She is already 11 inches though! Yay! (Assuming that measurement is supposed to be the tip of the nose to tip of the tail)
