In my experience, lust is the single most difficult obstacle to overcome in this whole self-actualizing thing. Attraction and lust are hard wired deep inside us, since we were very young kids.
What has helped me in this regard is realizing that I don't lust (or fantasize, crave to date, marry, love, etc.) after women because I genuinely care about them: I lust because it serves myself and my ego. When I catch myself doing it and why it's happening, it's much easier to deal with these overwhelming emotions and it gets me back on track. I also realize that the woman's attraction is just her outer appearance: inside, she's a bunch of organs, bones, blood, etc. and that we're all going to get old, wrinkly, and die someday. Hope this helps.
