I guess not

Hmmm. Jim West answered my question with a resounding "NO!" But then I read this:

What about when you double up this heightened male interest for greater sexual variety in a same-sex relationship? Scholars have examined this, finding that only a third of committed homosexual male couples had agreements on strict monogamy and truly honored them. The other two-thirds had mutually established ground rules for extra-curriculars or regularly failed to adhere to their commitment to monogamy. In fact, in the openly non-monogamous relationships, the frequency of sex outside the relationship in the last year ranged from zero to an extreme of 350 occurrences, with a median of eight hook-ups over a twelve month period. Even the couples who pledged true monogamy, the range was from one to sixty-three “slip-ups” with a median of five. The corresponding numbers for men in heterosexual marriages are microscopic in comparison. Women settle men down. Other men do not.

So, I guess Jim is right...celibacy won't ever find a voice among the same-sex marriage advocates. It's hard even to find a voice for it among heterosexual marriage advocates...
