What prompted that disclosure? Could she smell the horniness emanating from Anon? Did he, as he noticed she was a woman, give off a vibe like a starving cartoon wolf imagining the main character as comprised entirely of sausages?
Sorry that you feel obligated to mention this based on your past experiences. I hope our interactions are professional. Please let me know if I step over a line... my jokes are sometimes a little off but never misogynistic maybe a little dark, but I work on it.
With that out of the way ... my Name is Anon, I am happily married. Now.. let's Beginn =]
Respond super excited, like when you meet someone who shares the same niche hobby than you: "I like girls too! So tell me, what have you found to be the best technic to eat pussy?"
In this case its a bit different but what i see is that everything is oversexualized but the effect of that is people are actually more lonely because every social interaction you have with anyone who could be a sexual partner automatically becomes strange.
Is that polite though? I get that it isn't explicitly rude but I pretty much only use that phrase as short hand for "why are you talking about this you fucking weirdo?" I think it's subtly rude at best.
Most politeness is about rephrasing rudeness in a subtle way. What OP's fictional coworker did in this fictional story is explicitly rude as it assumes the worst from meeting a new person, the most appropriate response would be something that is subtly, but noticeably, rude.
If a team lead, sight unseen, just tells you their sexual preference without any context or follow-up then yeah that's fucking weird and they're a weirdo.
