I'm a girl and yes I have blown up a condom like a balloon.
I was doing it at school and the teacher walked past, he squinted at me and said 'I hope that's not what I think it is'. 'No sir, it's a balloon' was my reply but I accidently let it go, it blew around before landing right in front of him. Got a detention for it, my friends still laugh at it today.

The condom part reminds me of when I was in highschool, the playing with it like its a balloon is fairly common for the guys so finding a busted one wasn't to unusual but in one case their was one that wasn't busted like a popped balloon. Their was a short way between two ends of the buildings by walking outside instead of going down the hallway. I found a condom next to the side walk. It was out of the wrapper and looking a little shabby (unrolled and a little weather worn) so even though their was no visual proof of it being used (I didn't see any fresh body fluid on it) someone at lease unwrapped it... I was like "I'm going to school with pervs!" and "I guess I should be happy the idiots even have those with them!"... and "if it was used....??? *squints at it from safe distance*.... Nah...nope, dont think so!" and then a few min later after thinking about it more... "I feel sorry for the custodian that cleans after us."
