"Gay Unions Shed Light on Gender in Marriage" from the New York Times, Science section, June 10, 2008:

"A growing body of evidence shows that same-sex couples have a great
deal to teach everyone else about marriage and relationships. Most
studies show surprisingly few differences between committed gay couples
and committed straight couples, but the differences that do emerge have
shed light on the kinds of conflicts that can endanger heterosexual
relationships….

Notably, same-sex relationships, whether between men or women, were far
more egalitarian than heterosexual ones. In heterosexual couples, women
did far more of the housework; men were more likely to have the
financial responsibility; and men were more likely to initiate sex,
while women were more likely to refuse it or to start a conversation
about problems in the relationship. With same-sex couples, of course,
none of these dichotomies were possible, and the partners tended to
share the burdens far more equally.

While the gay and lesbian couples had about the same rate of conflict
as the heterosexual ones, they appeared to have more relationship
satisfaction, suggesting that the inequality of opposite-sex
relationships can take a toll."
