Some guys are shy, and to be very honest, it's often hard to tell if a girl really likes us. It can be aggravating because as the males we are expected to do the hunter i.e. do the asking out... for this reason, it can be an extremely endearing attribute to ask him out yourself, directly. I'm sure, if he even has the slightest degree of attraction to you, that he'll say yes.
Another rule to go by, if you do, is that just because he says no, it doesn't mean it's a personal matter. And even if it is... even if he thinks you're the ugliest human on earth, so what? There are 6.6 billion humans on earth, let's just assume half of em are men, that's a HUGE sea of people, so if one gets away, go for another one.
I'm positive that to every single person on earth, there's at least one other human who is/would be attracted to them, but you'll never know who if you don't go fishing.
