You don’t need to judge yourself for the things you’re into. You’re not hurting anyone. And I can virtually guarantee that at least one of your friends is into something weird. Come to think of it, having such a strong reaction to the character who was into guys’ tears, might indicate they’re protesting too much and they’re actually into tears too. 

Your friends are far more likely to take ‘my friend likes sad scenes’ at face value than wonder ‘but what individual element of sad scenes does my friend like?’  

If they do start asking questions, you could say you like seeing guys be emotionally vulnerable. Most of us who like male tears, the single biggest reason is because we like the vulnerability. 

I agree with psychic_girl. This isn't at all sexual for me, I get an emotional thrill rather than a sexual one. There's the vulnerable aspect, the "taboo" aspect, but mainly for me it's about comforting. I have no desire to see anyone I know in tears -- the few times it's happened I was so caught up in the situation that there was no thrill, just an overwhelming need to ease the emotional pain. But when I see a well acted crying scene, I feel a strong desire to comfort that person (man), whether by holding him, patting his shoulder, or having him cry on my shoulder. There's a very strong sense of emotional intimacy from that happening that is more satisfying to me than out-and-out eroticism or sexual scenes. (I've often wondered if I may be demisexual or even asexual since emotional connection is much more important to me than physical connection.)
