Hi there,I am not sure that I really have an answer to your question apart form this. The only thing that I can suggest is that you do your very best to avoid any kind of material that might stimulate you.
Porn, movies, magazines and internet etc are all going to stimulate the desire. It simply is a natural desire that you have and you're probably not going to be able to get rid of that, the best you can do is to minimize it by being very careful as to what you allow into your head, then apply will power.
