Actually I have heard that TRUE homosexuality was frowned at... For instance the two 'saviours' of Athens (when democracy had just been instituted a tyrant-imposter retook the city, these two guys then killed him in public and got killed themselves) were true homosexuals and that was regarded very poorly and cause somewhat of a stirr in the city.

So men living together and becoming personal lovers with no connection to women were definately not accepted. But then one just has to wonder how many just 'did their duty' and married women, but the same can be said of all history.
