Lust - How Can it be Overcome?

I am an above beginner level meditator. I have been practicing Vipassana meditation regularly for the past 6-7 months. By regularly, I mean 1hr of sitting meditation at least 5 times a week. I have not been able to control my lust. I try to remain mindful during acts of sexual gratification, but I have very few moments of awareness. The rest of the time, I am just going with the flow. Although I am a lay person, I want to be celibate. Please guide me. I remember a story wherein Buddha said to someone how one should eat as if they are eating their own child having lost in a desert. Are there any such stories from Buddha's life/teachings regarding this subject? Basically I need some inspiration. Please share your experience if possible
