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.
Talk about sex is inappropriate regardless of orientation. A person explaining that they are at a point in their life that they are ready for or attempting to have a child is odd, in my opinion, but not inappropriate. Again, YOU are relating this to sex, not them.
