For some reason, that comment of yours is very sexy to me, and humorous (even though that probably wasn't your intention, so sorry for that), and you've made it quite understandable why you were sceptical concerning the orgasm retention / ruining thing from your perspective and experience.
stick your long cock inside a glory hole and wait for my wife to slide it inside her warm and fertile belly. you will see that the enjoyment will be greater and that sperm will bear fruit.
