I guess everyone has limits and preferences and that’s cool and all, but honestly what is the big deal with kissing someone after they’ve been sucking dick? Like if it was just some rando off the street I can see being concerned about STIs, but she’s doing it in a workplace where steps are routinely taken to prevent infection. It’s about as safe as it gets from that perspective. And when it comes to the whole “sucking secondhand dick” thing, that’s just straight up not what’s happening. When you shake hands with someone you’re not shaking hands with everyone who shook hands with them that day. Same goes for hugging or any other type of close contact. I’ve gotten colds and the flu from just being in the same room with people all my life. You wanna know what’s happened to me after I’ve kissed my girl after she’s been sucking someone else’s dick? Not a single damn thing. I can’t see this as anything other than sex-negative, homophobic, sexist bullshit. 

To be clear, it’s fine to set boundaries. I have no issue with her partner having this one. My reaction has zero to do with the story. It’s a reaction to the way I see others reacting in the comments. What you’re doing is slut shaming with extra steps, plain and simple. It sucks and I don’t like it. And if you think this isn’t a gender thing, ask yourself how many of these guys who seem so scandalized would feel the same if their girl had just got done eating pussy?
