[bryony]

That's a good question. I'm not sure how I feel about it. I really don't see it being much different than now.

Right now, I sometimes want sex and sometimes don't.
She sometimes wants sex and sometimes doesn't.
When I want it and she doesn't, I go to sleep frustrated.
When she wants it and I don't, she makes me want it.

So, really, the only change I see from a reduction to my libido is that I'll be going to sleep frustrated less often.

Exactly. You may even find that if your wife realises that she has to initiate it, it might happen more often!
