My wife and I had many reasons for why we ultimately chose not to co-sleep. One of those reasons was our sex life. I don't pretend to know what the "norm"/average is, but it's frequent for us, 3-4 times per week, and at the risk of TMI, it can be fairly... involved. We know a few couples who co-sleep and I've always been curious how, or hell, even if, it has impacted their sexual relationships. Clearly it works for them (and you) and that's great! I would just be interested, if you're comfortable sharing, to hear what your experience has been here.
