I am a good bochur, learning, and I was very chizzuked up from guardyoureyes since age 14 and a half, now just turned 17. Since I started working when 14, officially becoming Shomer habris half a year later, I've fallen less than 10 times, but it doesn't mean I haven't fallen. I still have problems with shmiras einayim, particularly on the train when I go to see my beloved Rebbe. He cares about me, and I asked him about this, but I gotta go to the experts when it gets this tough. I sometimes end up too close to women, and one time even worse, a woman was "too close" to me and I didn't do anything about it. Nothing usually leads to shichvas zera, but its disgusting! I am "that kid" who is known as the nice talmid chochom and there I am letting go of myself like that, sometimes even putting on a regular hat and tucking in my tzitzis not to make a chillul Hashem. Its not fair to the people who hold me so highly and ask me to daven for them. I don't mind being in a position of respect if thats where my Rebbe wants me but I know at the same time that I personally, between me and G-d must DESERVE it 100%. I really don't like the "fakers" who aren't willing to work on themselves and schlep kovod from bochurim while they continue in evil ways, and this is what I've been, so help me rise higher, so there won't be any more of this nonsense and so that I can get back to my avoidah, to be a good chassidishe bochur that my Rebbe pushes me with so much love to be!

What a beautiful post!
I rode the NYC subway for years, so I know what you're dealing with. (Except I didn't try to stop lusting until many years later, I just enjoyed the ride.)

These little encounters with women on the train are certainly a nisayon. Ideally, you want to be pro-active in positioning yourself in a way that it can't happen. Go in with the attitude that this is a test, my test. We go into tests prepared.

If we feed our lust in any way, it will demand ever more.

Keep wearing your beautiful yiddishe levush. Our goal is to make the pnimius like the chitzonius, so there's nothing at all wrong with how you dress, even if you're not perfect. Trust me, no one is perfect in this area. We're all struggling to be heilige yidden.

Shteig on my friend!

that sounds like a tough situation. you sound like you are probably doing better in general than i am, but maybe a couple small suggestions from an outsider can help. first, and most important, say a small tefiilah before going on the train. Hashem, its hard for me in there, lots of nisyonos. I don't want to look, but i need to take the train. Please help me in there, etc etc. Say what you said in your post, how you really don't want to look, you just need His help.
and go in with a plan like alex said. bring a sefer, position yourself in a good spot, and realize that other stuff isn't shayach to you.
easier said than done, i know. and G-d willing you'll have some success, don't get complacent. keep up your guard.
Hatzlacha rabbah, its tough but Hashem can help you do it.
