i was bathing my female spur thigh when something came out of her ,then went babk in again.at first i thought she was doing a poo ,then realised it was something i had never seen before ! any clues ?
I'm not 100% sure, but I'm guessing you were finding out that she is a he. That was probably a penis you saw.
To be sure, do a google image search for tortoise penis.
PS. It it's not a penis you saw, you may have been seeing a prolapse of female organs. If so, you might want to see a vet to be sure there is nothing serious wrong.
