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.
We also use “I’m trying for a baby” as a euphemism for sex. In fact, my favorite euphemism is “just dropping the kids off at the pool”
“not trying for a baby, just through the motions.”
