That's one thing I've never understood.
Many human men vocally utter these retarded confirmations of wanting to fuck women constantly for no fucking reason.
It serves no purpose and just brings open satisfaction to the female.
Perhaps it's an outdated mating strategy for men, before the age of cellphones and the internet.
Notice how whenever women comment on how hot a guy is in comment sections its in hopes that he'll see it? I think some men subconsciously do this as well. Hoping that it'll bring the woman some satisfaction for whatever reason.
My other theory is that this is an action only done by Npcs, or those with no inner dialogue. People who can't help but speak their thoughts aloud, as if reading from a pre written script.
