Whats up Xingyl Fighter? I'm in the same position, I believe not having a father present most of my childhood and being raised by my mother soften me up to a point were my confidence is shot. Throughout my childhood I was always "stared down" by women and even popular women in my grades. They were always nervous to say anything because I was a loser/nerd "a good looking nerd" = weird and not cool. I know. However as I grew into man hood I started to gain confidence in myself little by little. Sometimes women stare for many reasons, they could like you, they probably think they seen you before, or they probably think you look like the rapist they saw on the morning news. Who knows? Women are complicated just like their male counterparts. The best thing to do is test the waters. If that chick is staring at you and she is pretty hot or OK, smile and stare back. It might be hard to start conversation because of fear of miscommunication or rejection, so a stare is easier on the soul. Try a smile or muster a simple hey to show some intrest that you acknowledge her as she does you.
I don't know why but women love to be noticed especially by that wanted special someone - its a woman thing! SOmetimes when women are staring at me on the 5 train, I do something goofy/funny to lighten up the mood. A good example; I was on the train with a friend, on my way home and I noticed these two chicks sitten beside me. One was Caucasian or Spanish - I believe, and the other was black with a large bottom (idk I find women with big butts and curves attractive, now and days its ideal to have a skinny looking model-like chick around your arm, however that's a different conversation and different day)
- back to the story -
I noticed the Caucasian chick kept staring at me, while her friend was talking to her. Now that's a dead give away, any women attractive woman that stares at you while her best friend is talking to her is looking for some good luvin. I stared back and smiled however I didn't make a move because she was with a friend and so was I. It was awkward! But when she got off her stop, as the train passed I looked out the train window and looked into her big blue eyes, she sticked her tongue out at me in a tease/playful manner and smiled - I smiled back and waved - lol "my friend was like did you see that tongue action! You got the Spanish [or white one] and I'll go for her friend [black one]" lol even though it never happened, however that one instance was enough to make my night, it gave me confidence to know that I am wanted / attractive. You are not alone - not all guys are matcho/ ubber alpha male confident - sometimes guys struggle with bearing the weight of being the alpha male. It is total fine - sometimes confidence comes natural to some people like my little brother and with others it grows on them, like you and I. I hope this helps!
