Trying on Condom for the First Time SeXStoRY

Again like my other stories this one is set a while back when i'm like 15 or 16. So the assignment in health class was sex. Not the good kind of sex, the kind where you get pregnant, die, get AIDS and get ****d by evil gargoyles with 25"chodes if you even think about having sex. But nonetheless we were gonna learn how to have sex and how to prevent everyone from dying the second their penis goes into a vagina. The homework for the guys was to properly put on a condom. (I don't know what it was for the girls, probalby to report to the coach's office after class so he can make sure that they all wore uniform matching panties.) So i get home and I have this rubber in my pocket. I go up to my room and get naked (awesome). So i pull out this cheap ass thing that would only probably prevent pregnancy if you have the sperm count of a 70 year old man. I get myself nice and hard by thinking about whoever i wanted to put my little pee pee in at that time and proceed to try it on. But there was a problem, it wasn't working. I kept tugging down on the rubber but it wouldn't go on as easy as they said it would. I pushed it down eventually but it was soooo tight and it was squeezing my cock at the base so tight that i thought i wasn't going to get it off. Then it hit me...it was too small, and then it hit me again....I have a big cock. So its easy to say now that i know for sure that i wasn't doing anything wrong and in fact it was to tight and to small but i'll never forget that experience.
