For research purposes, I kept a condom after use, rinsed it thoroughly with water and let it dry. (I wouldn't want to waste a new condom for the following experiment.)

I found it impossible to rip off the tip of the condom with my hands. Or to rip it apart in the long axis. You can easily poke a hole in the latex, but I couldn't rip it in two pieces.

Biting off the tip, however, is easy.

The story serves as a reminder to check if the top if using a condom, and if it's intact, when bottoming. Judging by the number of boys who offer to fuck me bareback, or who would get fucked bareback, use of condoms is in decline.
