The theory of "just do it" makes assumptions that the partner is at least willing to try. If the partner is not willing, IE, my own situation, the "just do it" idea is akin to rape.
I was the initiator for years in my marriage. I stopped initiating after one particular horrible experiance where I felt that I was raping a 10 year old boy instead of ML to my husband. He refused to talk to me to explain why it was so tramatic for him, and I never initiated sex again. That may be an extreme example of why I don't think that the "just do it" philosophy is not always a good idea, but it was my reality. This is why I caution you to be careful in using this technique.
