well, it comes down to what a guy’s intentions are. he may find you attractive and just genuinely wants to get to know you, he could be thinkin of just wantin to hookup cause you’re attractive. when you lock eyes it’s either nervousness/embarrassed or he’s thinkin you’re both on the same wavelength (at least this is what i’ve done before myself, so take it with a grain of salt 🤷)
For me personally (lots of guys aren’t like this) when I see a pretty girl I make sure I’m not being disrespectful (looking at her assets) and just kinda make an internal note of how cute she is then go about my day and forget about her. If we lock eyes I try to escape the situation asap😭
