honestly i thought those were the same concepts lol. suppose for a man the climax could be where he's close or at the peak, but the orgasm when he finishes. prob different for us ladies though !
i wouldn't worry about it. the older I get the more I don't think too much age is a big thing if a 44y man for example (bout a 20 year difference)So long as they want fun i think its ok imo
