Excellent thread!
I'm a complete para (T5, so no movement or feeling below the chest) and actually have a pretty active 'sex on the side'. For me, I get a great 'full' feeling when I getting fucked, and a lot of it is mental for me...it's a great turn on... (Not to mention that my nipples are my pleasure zone, which is why I had them pierced.)
I do find the quoted paragraph very familiar though. A few years ago I used to see a guy I met from Gaydar who used to visit me on his lunchtimes for an anon breeding. He always wanted me ready on the bed, blindfolded and lubed for him. Door open, he would come in, undress and fuck me till he came inside my arse..He would then present his dirty cummy cock for me to suck clean, and off he went.
We never spoke, I never knew his name or his age. I only ever saw his shoes once! I could pass him on the street and I'd never know. Heck, he could live on my street! It was always a massive turn on for me, but one day he just disappeared from Gaydar and I had no way of contacting him, which was pretty sad really.
I have seen plenty of guys, and some are very keen! Maybe this is a little 'niche' fetish?
I recall my very first time when I met a guy that I had been chatting to online back in...oh 1997 maybe. I met him at the South Bank Centre in London. We had a coffee and then proceeded to the disabled toilet where I sucked him off and swallowed his cum. I remember he had a very tight foreskin, and was a very nice guy....hooked ever since.
