For me its more about the entire thing then having an orgasm. A lot of the time I can orgasm in the first few min of sex, but if that's all there is Im not really satisfied. Id rather have 30-90 min (or more) of good play/sex then an orgasm. Though there are times where all I want is an orgasm, but they are rare. The only thing is DO NOT get me to the point of orgasm then screw it up! lol that gets me frustrated.
I guess it also depends on how often you have sex. If you only had sex periodically, then having an orgasm would seem really important but I have had sex every day for the past 6 weeks and if it doesn't happen I just shrug and say tomorrow!
