It means they’re having bareback sex and the man orgasms while inside her.
It should not be tolerated at the workplace. I’m forced to listen to this rhetoric because my shift isn’t done yet, and I can’t leave without getting fired. I’m forced into a sexual discussion without consent, and it’s so graphically disgusting that I feel nauseous.
This, folks, is a perfect example of projection. OP is a gay man and has worried that others judge him for his preference, so he judges others for the same thing.
The healthy thing of course would be to learn to let it roll off his back, and in calming that, he would calm his own worry about others judging him.
