What country do you live in? In most cultures the man is expected to be the aggressor. So the probability of a random woman coming up to you on the street is pretty small. If it does start happening tho, then you know you're in the top 5% of attractive men. Otherwise, if you want to know if you're attractive to women, start talking to them and see how they react. You'll know very quickly. A word of caution tho is that you might not want to know. I'm an ugly person, and I can say that I had more self esteem when I didn't know for sure.

Women don't tend to be obvious about checking someone out. Also if hitting over 100 wpm doesn't boost your confidence, I don't know what will.

Women are temporary. The glory of an over-a-hundred-words-per-minute is eternal.

Others are certainly checking you out. However, just like you they may not be confident enough to approach you.
