Being 'deep-throated' is sometimes the most incredible sensation, once I had a very talented guy deep-throat me for well over an hour, by the time I shot my load my dick had swollen to a size that I didn't recognise. I still go looking for him sometimes over Clapham Common where I met him, but so far I've had many many others almost as good, and I particularly 'Love It' when guys can't quite manage it all but won't give up trying..... choking gagging even vomitting sometimes, it might sound weird but it really turns me on.
The biggest problem I find though is being scratched, bruised or cut along the shaft, but I am lucky having a long and down-ward curving dick.... Ideal for having guys kneel before me.
