interesting discussion.
I am 53 and married for 20 years
I would say that I could easily be in the 'rather have a cuddle' box. I very rarely actively want sex, but what I have discovered over the years is that given the right approach, and a willingness on my part to see what happens, I can often be persuaded.
Once I have got turned on, then I really enjoy it.
One other point is that I am always tired and wanting to read/sleep at bedtime, but have discovered that morning sex works well for me.
So, we could have settled for a low/limited sex life, but because it mattered, we have explored and tried different things, and now we have a good sex life which we both enjoy.
I think it is misleading to say women 'give in' and have sex, I am sure some do, but I am also sure that sometimes it just requires a bit of effort to get on board and enjoy it. of course we are free to say no, and not to want to make the effort, but that is true of many things in life!
Since kids are older, we don't have broken nights, and teenagers lie in on Saturday morning, we are finding a whole new dimension to our sex life, but that coudl just have easily not happened, if we had given up on it.
