Thanks for the comment!
In my publication I said that sex is not a means for manipulation and not an obligatory requirement. I do not want to think that relationships are built primarily on sex. I do not think that it is worth thinking very narrowly - if there is no sex, then a person is no different from a friend. Friendship and relationships are different, even without sex. These are different roles, expectations and quality of interaction with a partner.
If we talk about sex in relationships, here I agree - do not be shy and be silent about your needs. Everyone has a different constitution. Someone needs sex once a week, someone several times a day. Sometimes partners simply do not fit together in physiology. But this does not give them the right to demand more or less sex from a partner than he can and wants to give.
P.S. My comparison with chocolate was ironic. You say sex allows you to reduce stress and anxiety, but chocolate also. This is a different way of getting calm, relieving stress and getting pleasure. And eating chocolate, too, does not always have only the physical component — a famine.
