It can pocket a few times together for two people to capture used to one another's preferences in bed, but after that it should be possible each time, provided in that is open communication between the two partner and both are interested in the other's pleasure.
It if truth be told took me a long time of having sex to realize that I be the one responsible for having an orgasm, if I looked-for one. A girl can diddle herself during sex or ride a guy at the angle/speed she wants, so it's not entirely up to the guy to GIVE her one. Women entail to be more proactive if that's what they want. that said, I don't necessarily have to enjoy an orgasm every time I have sex, it can be substantial even without orgasm.
