Talking from this mans perspective I've always found that if during sex i don't get to cum for whatever reason I get really arsey. I know it can make my day go down hill big time until things are either rectified or else the onset of sleep occurs, whichever is the sooner,
Together with this is there times that you are so horny that you think (in the case of a bloke) when i cum i'm going to blow the top off my tackle its gonna be that big and powerful a cum, but when you do its the opposite. Always nice still admitted, but non the less, less than the expectation.
Conversely there are times when the power of the cum really takes over and is a complete surprise and its just the most amazing cum. Long and powerful, leg wobbling, eye out of focusing silly noise making ones. Do other others find this?
