It's much more important to US that a woman has an orgasm than it is to women (at least that is what my female friends say).

Men tend to put alot of emphasis on her orgasm. Unlike men, women can enjoy sex without the release. SURE, they WANT to have one every time but if you are giving her what she needs (in AND out of the bedroom) then you have no problems.

Increase foreplay/oral and make sure he finishes BEFORE you start....just a thought.
