>is it really hard for guys to ask girls out??
At the beginning is difficult, with practice you become mentally prepared for rejection.
>is it kinda scary for you?
Yes, it always is. The best way is not to think about it.
Now let me ask back:
-Is it hard for girls to reject a guy they're not interested in?
-Are girls concerned about what other people might think of them if they were to ask a guy out?
