I've never used them in that way. But I do call people pussies and bitches sometimes. Given the wide range of targets I use them on I'm not sure the application, intent or context I use them in is sexist. So is using the word 'pussy' sexist? I often complement women on having lovely pussies... is that complement sexist...? Lets go deeper... some examples! 'urrr I don't think I should have a 2nd beer guys, its 8pm and I'm tired.... Jeff, don't be a pussy, I'm getting you another pint.' Is it sexist towards Jeff because he might have small balls and is acting like a bit of a bitch? :P orrrr how about this one... 'all THEY are good for is their pussy', which one is worse? I'd hope you'd say the later, but still I think the offensive bit isn't the word 'pussy'. In fact you could change it to 'ovaries' 'cooking skills' 'tits' hell a bunch of things and its still offensive because of the application, target and context. tl;dr I don't think a word can blanketly be called sexist.
