Has it ever happened to anyone doing straight sex?  Greek?  What percentage of the time does it break?  I'm hoping almost never! thanks

It reduces the friction and thus lessens your odds of breakage... kisses ~T

150 degrees. Extreme cold or heat can make condoms brittle, and more likely to break.

Vuctoria is right, use lube and reduce the chances of a condom splitting.  It's never happened to me with a client but did happen with a boyfriend a few years ago.
