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.
Are they going into detail about their sex or did they just say they were trying to have a baby?
If it’s only the latter then it’s about as inappropriate as women showing their bare ankles in public and you may be overreacting just a tad.
ETA: please answer this question.
