It is a valid point. Sexual intimacy is a need. It isn't on par with food and water but it is a need. Hopefully in a constructive and loving marriage both partners try to keep the other engaged in the manner that Simon indicated.
However, sometimes things aren't going to go as smoothly as we would like. Usually I am more than motivated to jump his bones. However, if I am not feeling it for a while (for any number of reasons that have nothing to do with the quality of our relationship) I don't abandon him.
I think maybe we get too hung up on gender roles and female empowerment that precludes submitting to your husband's authority. My husband has no authority over me (quite the opposite). We are partners. Why is it ok that I insist he spend his saturday morning trimming the hedges but I won't touch his dick unless he executes a flawless routine of sensitivity and sexual motivation?
You want to be liberated? You want to be equal? Grow up. Recognize we all do things for our partners......that is why it is called a partnership. You aren't in the mood? Well guess what, he wasn't in the mood to trim the hedges either. Hopefully most of the time it is romantic and sexual magic, but insisting that always be the case is juvenile and selfish. Don't be above sucking that cock to support your partner.
I think I like you.
