6. By touching him lightly while smiling at him
“I can’t help but get flustered and start to wonder if she might be interested in me…” Even if there’s no deeper meaning behind it, this kind of thing gets a man all worked up and confused, so it may be worth thinking carefully before touching a man out of the blue. It’s possible he might even come to think, “She’s always all over me!” so it’s probably best to just avoid physical contact altogether with someone you aren’t romantically interested in.
