I think you have made the mistake of linking your sense of self worth to the frequency with which you have sex. Your worth and beauty as a person and a woman is not connected in any way to anything outside yourself. By all means, enjoy your sex life but don’t measure yourself or your value by it. Just as you would not want to have to make love when you are not up to it physically or emotionally, you would not want to demand that your boyfriend make love with you when he is too tired or stressed or not feeling well.
If your feelings for him are genuine you won’t feel less loving towards him on days where you don’t have sex. How does just plain cuddling work for you? I’m sure he does not care for you one bit less on such days.
If your feelings for each other are absent when you don’t have sex, your relationship needs to be ended. I doubt that is the case.
By the way, six times a week is very frequent and many couples are happy even with much less frequent lovemaking. Do what works for the two of you and enjoy all the good things about your relationship.
