Great old thread!

Man 1. You know that scene in American Werewolf in London where the main character changes into a werewolf, making those prolonged, pained, loud growling noises? Well, I fucked a man who sounded just like that when he came. It was alarming! I was half expecting him to metamorphose into something unearthly 

Man 2. 2nd date, back at his for some how's your father, and as he was banging me over the arm of his sofa said "All for you, babe, all for you". Just as well I had my face planted in a cushion as I had to stifle a snigger as it just sounded so pornolised and ridiculous. I'd already thought we weren't a match made in heaven as he was a bit full on, and decided then I wasn't going to stay the night, but to make it easier for me to "escape" I waited until he was asleep and snuck out. Then avoided him like the plague.
Man 3. Told me all about his amazing hand technique that he said gets all the ladies off. Well, it didn't do much for me, so that coupled with his bragging about it was the end.
Man 4. Whenever I was on top he'd order me to "Ride it! Yes, ride that cock!" repeatedly. I just wanted him to STFU. Can't stand porno speak, it sounds so fake. Saying that me and one of my later partners used to do to each other for a laugh. It would have to be in doggy so I could turn around and do the whole "Oooh yes, baby" (whilst sucking air between my teeth) while he would say "Ave it" in a fake cockney accent 
There are so many more (I have rather high mileage!) so all different shapes and sizes. The most troublesome have been the above average sized where they just hurt unless there's been tons of foreplay and the owner is skilled. Unfortunately I've found that those who have big cocks seem to think that just the sight of their magnificent peens is foreplay enough
Hate it when I can't even get them in my mouth too.
The cone-shaped ones are tricky too as condoms keep wanting to unroll. I pretty much don't care how big they are provided the lovers are eager to please and can follow instructions.
