It is seldom that any girl can truly understand what goes on in a guys mind, but for the sake of clearing something up that bothers me I thought I'd share my two cents. However, this won't apply to everyone and is based on personal experience and basically what numerous guys would, in actuality, agree with.
I'm going to be frank, if no guys are approaching you or the guy you want doesn't approach you its him, not your looks. I really don't think any girl will understand the mental chaos that a guy experience when he even considers talking to a girl he likes or simply wants to ask out on a date. There's so many factors that guys have to take into consideration mentally before even thinking of taking the first step towards you, including how we look, if we are nicely dressed, and if we smell good that very moment. Additionally, the fact that guys are expected to pretty much always make the first move pretty much exacerbates the problem and makes it worse leading to more guys having a fear of rejection then most girls.
Without getting in depht, here are mental quotes from your average guy looking to approach a girl.
"What if she says no?"
"What if she rejects me humilatingly?"
"Probably likes someone else"
"Probably has a boyfriend"
"I'll ask her out the next day"
"I'll wait till she approaches me"
"What if she thinks I'm to ugly?"
"She looks busy & I shouldn't distract her"
"What if she thinks I'm weird?"
"What if I humilate myself in front of everyone?"
"What if she notices (insert insecurity)?"
The fact of the matter ladies is that you have no fucking idea how nervous we get when we even consider approaching you. I personally don't think any girl will truly be able to fathom how shockingly difficult it is for a guy to approach a girl he likes, even if he's jaw-droppingly good looking, popular, or anything similar. The truth is that guys are conditioned by society to make the first move which doesn't whatsoever.
So this is my mytake, I hope I shed some light on how guys like me feel when we want to approach a girl we want to get serious with or even just want to talk to.
