Annie, without wanting to be needlessly pedantic, it depends how you define 'the church'; are you talking about clergy, or bishops, or General Synod (which is made up of clergy, bishops and laypeople)? Or the small groups which are put together to discuss specific issues and recommend a way forward on them (which is what happened with this latest legislation)?
The reason I ask this is because many clergy and bishops are bored and embarrassed by the various sexuality debates, many wish that we could all just move on. I can't see, in all honesty, that they are any more penis-obsessed than anyone else.
I think it's more accurate to say that over the last decade, sexuality has become the litmus test of whether someone is 'liberal' or 'traditional'; why it's ended up as such is a really interesting question. But the reality is that debates about sexuality have become a shorthand way of defining subgroups within the C of E, and the real problem beneath the surface is the fact that within one church, there are people who profoundly and maybe irreconcilably disagree with each other. That's why these issues haven't been solved yet, and it's why the impression of the c of e is often exactly what you have described, that we're all juvenile misogynists obsessed with penises.
Some people think that the only real solution is for the church to split; I am against that, as I believe that Christians should be united. But it is hard, and Rowan Williams really got sledge-hammered with the full force of the church's internal politics.
