My husband and I have very different views on sex and frequently - his drive is greater than mine (we’re both mid-30s), and we have a 3 year old son but looking to try for another soon. The last 3 years have seen frequency drop a lot. My husband works away and on shifts, so when we’ve spoken about it, he says a reasonable, realistic view would be once per week, but even still, I’m not sure. How often does everyone else do it?
