I agree with @Sub.Zero
Attraction is not negotiable.
What does this mean? A woman views a mans sexual market value in a whole manner of ways (unlike men who only care about beauty).
These include leadership, social calibration, looks, money, charisma etc.
Therefore in order to get your wife to go from starfish duty sex once a month, to ready whenever you are in the mood you need to improve in all these areas that are lacking.
And if you level up in theses areas other women will also desire you and this has a two fold affect on your wife.
-
It makes her happy that you (the prize, high value man) are fucking her which increases her attraction to you.
-
Other women (possible competitors to her) also want to fuck this high value man, therefore I must always put out in case another woman catches his eye.
Therefore cuddling in bed, watching movies etc is just beta Bob, the oestrogen slug becoming her gay best friend.
This isn’t going to get her wet.
