4 weeks wouldn’t bother dh and I at all. We are very well matched and have been together nearly 10 years and sometimes we have it a lot and sometimes hardly at all! We have stressful things in our life - disabled child, health issues, mum just died a couple of months ago etc etc. Lots of big issues and sometimes life gets in the way - we’ve been through a lot together. Sex is important but it’s just part of a whole relationship.
We watched it and although yes it’s just crap telly it seemed sad they were all so quick to say their relationship had gone down the pan because they stopped wanting to shag each other every few seconds. That’s just long term relationships for you!
