I’d suggest that you start thinking about your future wife (you probably will find her, and soon). . .how do you think she’d feel about you looking at hot girls? The trouble with “looking” is that you lack discipline, and the more you look, the more you want to look, and further. Why not try writing down some of the characteristics you would most like in a wife–and it WON’T be that she is “hot”. . .wouldn’t you prefer a wife who is modest, kind, loving, generous, thoughtful, practical, open and giving yet quiet and selective. . .etc. See how many characteristics aren’t the “physical” lust arousers, but instead give you a real idea of the kind of “love” that a marriage will bring. . .not, “gee, sex every night” but “gee, a total sharing, warmth, mutual respect and trust with someone who is a real part of me”.
I know guys are more visual, but hey. . .
You could always read some real literature, esp. C. S. Lewis. Try reading his trilogy of “Out of the Silent Planet”, “Perelandra”, and “That Hideous Strength”. The last book, especially, gives wonderful insights of marriage.
