with Chicup, if a woman told me I couldn't have an orgasm with her, I would pass. I have to say that when I am having sex with someone, my ultimate goal is for both of us to have an orgasm, if that isn't in the game plan then I don't see the point in having sex in the first place. To me that would be like going to Disneyland and not going on any rides.
As to the OP's original question, I have in the past played so long that I just didn't have the energy to reach an orgasm, after that time I made a vow to myself never to do that again. While I would somewhat agree that the lifestyle isn't
all about how you finish, if I don't finish, for whatever reason, I am going to be disappointed.
