All over the web ther are videos and info on how to sex your BP. Now I was told when I got my BP it was a male (from a pet shop)
After reasearch on how to tell I thought it was a female. Our vet said he would not sex her (at 2-3 months old) because she was too young. I know that is wrong, because I have seen breeders sexing thier snakes shortly after they hatch.
I watched many videos on "poping" and after many months I thought I would have my husband help me and try it. Well her/his tail is quite hard, so poping is out of the question.
The reason we guessed it was a female was the tail size way.
"males will have thicker, longer tails than females."

So my question is, Can you tell for sure your snake is a male or female without probing, or poping?

Also my snake, when i run my fingers down her/his tail end he/she wags her/his tail. (I have long nails but I am careful not to scratch)
Does anybody else have a bp that does this?
