I dont prescribe to the stated excuse for using non traditional terms in the OP. In my experience These various labels tend to be used just to spice up the sex talk. I've used these terms myself on blogs as it gets boring and redundant always just saying cock, ass, pussy. Even these terms are slang, as it's more fun than saying penis/vagina. So I don't care if someone mixes in some 'twat' 'cunt' 'schlong' 'dick' 'brown eye' 'pink eye' 'purple monster' 'meat stick' 'pleasure pole' 'taint' 'tgirl' 'shemale' 'tranny' 'breast' 'boobs' 'melons' 'tits' 'rising dragon' 'velvet glove' 'spitting cobra' 'pink abyss' ''whispering willow' 'cum' 'cum guzzler' 'cum despensor' etc. I can really go on for some time with all the slang terms I've heard since high school lol Point is there are a ton of slang terms that would also need to be cut out to be as pc as the OP would need.

I had an awesome song to play with this topic but my net is down with storm and viewing from my phone.
