great question @purple
I’ve had this experience when the sex has been really heavy as in super fast and lots of motion and I know the condom was on the right way. Maybe this could have happened?
No matter how many times you pop one on should always check it’s up the right way and also that the condom is the right size for the penis, if the condom is a little too loose than maybe this is contributing. Definitely talk to them about application and also the plan if the condom breaks.
