I took him to the vet (spent $71) for him to tell me it was a seminal plug. It did feel hard for the 1/2 second I touched it to put it into a baggie for the vet to see.
Just to answer the other questions, though, he never blackbearded last night or today, BUT he had been a little bit over the last several days. Didn't really put it together until now. Wonder if that is why..
I don't know his true age, but he was an adult (hasn't really changed in size or weight) when I got him. I think that was around October/November of 2007.
I am sooo relieved, Poor guy, I thought somehow I made his little weenie fall off!! lol
One part of me thought that, but the other thought, wellll, he's not bleeding so 'i dunno'..
Thank you so much for your quick response, I feel much better since he still has all his parts!
