Sex used to be very important for human tribes when they developed their languages. Having to provide type of sex is an annoyance when sex does not matter. The word 'it' for a woman or man is still not acceptable.
Some humans misuse the word cat, dog or pig for a person to reflect emotional feelings. The misuse of words says more about the speaker.
The last question is unclear. Time will come when all spoken languages will be replace with a worldwide language that is clear.

at times i even refer to man or woman as mann or frau - i hope that's still ok in our day & age, if not exactly pc. people make too much of language & not enough of practical kindness. as for using another for anything: don't we do this all the time? it only gets nasty when the other isn't really into it, not agreeing. otherwise, go for it; use each other for sex; enjoy!

Referring to women as 'females' is incel/MRA/etc talk. Also, in my mind it sounds like the Ferengi from Star Trek, every time.

I don't care, though, if I'm addressed as 'dude,' 'cat,' 'dawg,' etc, and I don't object to being addressed in a group as 'guys.'. To me, 'dude' is so agendered that it's used for inanimate objects.

As to the third question, I'm not entirely sure what you're asking. Sex workers?

I do call to men; dude, boss, chief, man, bud and in rare occasions pal (snidely). I don't mind being referred to as a male or any non-derogatory word. I try not to refer to women as 'female' because most women don't like it but sometimes accidentally I will say ; gal, lady, girl. The one thing I don't like is addressing a mixed group as 'guys', when I was working at the center I referred to a mixed group as 'kids' . I was much older than them plus I was in charge of the group so maybe they were too timid around me to complain.

Please ask one question at a time! You are rambling again !

You have like three questions in one.

• No, no problem with male female
• also no issues with pet names
• yes, using others for sex without their knowledge is wrong. If they both agree then it's fine

I have been called dude, I am a woman and that felt awkward. Thatsabuncha questions in one spot!
