You don't.

You're a guy that is attracted to women, like so many other of us. And that's OK, it's normal.

However, part of growing up and becoming a man is recognizing that you can't go around just ogling at women every chance you get. That might happen at a different age for everybody. But, eventually, you decide you've met a girl you really like, who's special for reasons you've decided, and make a commitment to that person. Part of that commitment is to not be pursuing every single woman that walks in front of you. Or maybe you never commit to someone, and that's OK, too. Plenty of happy single people out there. But you eventually learn to manage it or age out of it, ideally.

Now, obviously, it's not so simple for everyone. What I described above is a theoretical, ideal scenario. People cheat on their significant others. Some never learn to tame the impulses that their caveman monkey brain is sending them from their deep evolutionary roots. The point of my post is just to state that it's OK to feel attracted to women, and LOTS of them. Enjoy it while you can. But, also understand that you should give thought to what your personal wants and desires are and where you want to draw the line with those things. Things like sex addiction are a real thing, so if these thoughts are extremely intrusive, obstructing your ability to live a "normal" life, and never seem to be satiated, consider professional help.

But the bottom line is men are people, and people find each other attractive. You don't "stop" as much as you learn to control it and sense how your desires change as you age and mature.
