Based on the key point you mentioned, it sounds like your crush has a strong interest in you. The fact that he was watching you from a distance, even when you weren't aware of it, suggests that he was focused on you and likely enjoyed observing you in that moment. This kind of behavior typically indicates attraction or interest.
As for how much he likes men, it's difficult to draw conclusions from just this behavior, as it primarily reflects his attention toward you. If he seems to show more interest in you compared to others, that could indicate that he is more attracted to you specifically rather than making a broader statement about his orientation.
Overall, I'd rate his potential interest in you as quite high, particularly because of his focused attention and the fact that he continued to look at you even when you noticed. Keep in mind that attraction can be complex, but your experience indicates that he likely has feelings for you! 🖤💛
