Odd words don't worry me over much as long as they aren't repeated over and over, then they get on my nerves, they are of course, (being English myself).

'Pussy' Jesus H Christ, it cracks me up, "Arnold thrust his quivering manhood deep into her pussy", hell's bells you get locked up for shagging cats over here.

'Ass' (spelt wrongly) "Arnold eased his dripping wet pork sword out of her pussy and rammed it up her ass" Yee Gods I thought he was bumming the bitch not screwing her donkey, I'm not into beasty.

I don't mind 'Butt', I prefer 'Arse' of course instead of the donkey, 'Pussy' as I say is Ok in small doses, but being a cat lover I don't like to see them get too much abuse. 'Knickers' is fine by me, but 'Panties' again moderation please, we put 3 yr olds in panties over here, women wear knickers.

The usual idiot names for the tool and orifice are a turn off. Anything using 'Throbbing' or 'Monster' or 'Quivering' etc, etc, is out.

I use slang terms and the odd over exaggerated description as humour breaks occasionally myself though I must admit. 'One-eyed-Bed-Snake', 'Trouser Mamba', 'Dripping love chamber', 'Cream filled fuck bucket', but only in light hearted stories.

Normal words that I use commonly and don't object to at all are:
Prick, cock, dick, cunt, fanny, twat (occasionally), vagina and penis are Ok but make it all sound a bit clinical or like kids sex education. Erection is nice in a moderately high class story, but hard-on or bone-on is the best for dirty tales.

My big turn OFF and immediate reaching for the back button is of course the idiot story teller who insists everyone in his/her tale is Mr/Ms/Mrs perfect, and said story teller has carefully measured each character to prove it. Each character of course makes the average reader feel very inadequate.

"Arnold was 6ft 3ins with a 42in chest and weighing 190lbs, his throbbing manhood was protruding to the full 15 inches as he offered it to Marcia, Marcia lay naked in front of him, her 38DD breasts and perfectly formed flat belly along with her incredibly shapely hips and legs causing Arnold's 15 inch monster mamba to quiver and pulse, pre-cum dribbling from his massive purple helmet eye" Oh really, CLICK!!! (What the fuck's pre-cum anyway)

I like to make my characters attractive but somehow normal and attractive, "A big bloke, quite muscular" does for me, "Above average weapon" no silly precise measurement and let the reader decide what average should be. I prefer my woman to be normal as well, "Well put together", "Nicely formed", let the reader do the thinking and visualising, they like that.

Most of my characters aren't perfect, I'm not perfect and I don't expect them to be, I don't go out of my way to make them ugly, just normal "Slightly pot bellied, but not overly so", "strangely small tits for a woman of her general build", but I like little tits, so do a lot of people.

Just a few observations from old pops.
