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.
It might be a cultural thing, but where I live, people usually don’t talk about it at work until the pregnancy has been successfully confirmed, in order to avoid the uncomfortable talks that a potential unsuccessful pregnancy would result in.
The only ones who talk about trying are often the ones who have difficulties with it. They could be getting a baby through insemination or fertility treatment and need time off for that etc.
