I wish I had knew these rules when I was younger, I hate to say but I was a creeper when I was around 17-19. Asking women strange and personal questions,staring, following them to closely. I think the problem is that I was intimidated by women, I used to see them as alien and weird and never spent much time around them before coming to college. And even though I'm now more confident than I was a few years back, I still occasionally make a few mistakes.
Shy Guys, the key to getting girls is simple: treat them like human beings, talk to them like you talk to your friends. Also, try too meet girls that share your interest, and have attractive personalities, rather than based solely off physical attraction(although that is important of course) and social status, and what society tells you is attractive. And also stop fearing rejection. Each woman is different and has her preferences of what is attractive and not, one group might think your ugly, another group might think your hot, so if you get rejected it doesn't mean there is anything wrong with you. For every woman a mack or a player beds, there are 10 women that rejected him, but they don't care, because they know in the end, they will get some.
