Sexual pleasure is a strictly physical things. The emotions that go along with it play a part but are different things.
A machine should not be able, nor care to have the physical portion of it. So I agree, the EMH should not have been sexualized.
I think the writers were basing this on fan's acceptance and fascination with Data's "fully functional" capacity. While that annoyed me as well, at least with Data we never got the idea that it was true enjoyment, but rather more like "imitation" of human behaviour.
