But that is your personal preference. Everyone is different. To be honest, any Dom who intended to increase sexual desire who found it not working would change tack - this is why you negotiate and communicate. For many the allure of something that is restricted or forbidden is strong. I have known women who get INCREDIBLY turned on during their period partly because they rarely get the chance to have sex then. It all depends on how you relate to sex in your own psyche. Some find chastity easy because their desires just switch off until needed. Others find it very difficult. Some think they won't get horny when on CR and are surprised when they do.
