I'm 44, DH is 50, we have two children aged 5 and 3. We have sex maybe once or twice a month usually when I am ovulating because that's when I'm in the mood. We both have busy jobs so I think we just feel tired. I don't really feel interested the rest of the month. DH doesn't seem bothered either but if I initiate he seems pleased so I think he knows I'm only in the mood infrequently. We've been together 20 years now and have young children so this feels okay. Sometimes I think about those beginning stages of our relationship and miss it but I guess it's normal for a relationship change? I also know that there's no normal and if we're happy then it's probably fine.
I wondered how common this is.
