Well don't be too sad. I remember when I first tried popping.. I tried it on my female a few times just to see if she was sure to be a male then when I tried to pop her instead of penes coming out, I was peed on. It just shot out and I didn't even expect it. Kind of nasty too, it hit my neck and some of my hair. I took a nice shower that night though lol
I was also peed on by my Corn snake when I tried to pop him.. and from my Kingsnake I used to have. Snakes seem to like to pee on me for some reason..
