Just today when I (24M) was dropping my female "friend" to her house, I caught her staring at my bare thighs. Basically my shorts were riding up as I was driving. I immediately heard her breathing heavily and I could see she was trying to speak but getting breathless. This is not the first time this happened to her around me!

Now I've never made any moves on her because I was afraid of ruining our friendship for casual sex but I'm sexually attracted to her. Is this a sign or am I just thinking too much?
