It really is all about whether or not you do it right:

Failure rate is 2% when you follow all the instructions, 15% when you don’t. Most of the bad stats come in because humans just aren’t that great at following instruction at the best of times, and we get much worse at it when the hormones are flowing.
2%. That’s what I thought though I didn’t have the info at my fingertips to put it out there. It’s a very high effective rate IF you use it properly. Problem is, people don’t.
BTW, if you are against birth control methods, I totally understand. I’m only writing about effectiveness.
Sorta true, sorta false.
The correct methods include checking for leaks after every, uh, input, and holding the condom on by pinching the base of the uh, nozzle throughout. I submit that no-one follows those rules.
