25 [M 4 F] Cali Ladies, have you ever caught a guy friend or stranger get hard around you??

For example, one time I went to visit a home girl in college. She kept walking in front of me and on that day, anything was enough to get me rock hard. Needless to say, I did a lot of uncomfortable walking and hiding through out the day. I feel like there’s no way she didn’t see it cause it was so hard to hide. How often does this happen?
