Yay! Another Aussie!
How often are you actually having sex? I have found that if you are having sex all the time (Say everyday) with the same partner it can get a little bit stale & some of the excitement is lost.
Also, does he initiate the encounter or do you?
Personally, I have never had a problem rising to the occation

but if he is saying there maybe stress involved, then maybe you should not force the issue.
Sex in all it's glory is ment to be enjoyed by both parties. So if he's not in the mood, then give him his space. Of course, that street goes both ways
