I have no idea, it's been more than 30 years! It was back in the 1970s after Angie. I was first told of their existance in a health education class (not that I listened). Then my grandfather and finally Lou Miucci who called them prophylactics. Miucci then drove me to Miller's pharmacy down in Stapleton where the owner (?) of the place and Lou explained the full function of a condom and how it worked. It was more than a little embarassing to me. To prove a point, a flashlight was used for a demonstration and as a reminder that they could fit most anything and still not break. Horribly embarassing. Lou then drove me back to 1208 Bay and told me not to forget what I had learned or to go wild trying out the new knowledge. Over the next decade-until well after I'd graduated high school- he would remind me to always use a prophylactic when engaging in sex.
The first time I used a condom, it felt strange and it took me forever to cum as I kept wilting as I kept envisioning the two men who used a fucking flashlight for a demonstration. Eventually, the girl I was with begged me to stop and she then finished me off with a b.j. The next time, things went better and have for the most part since then.
