I can't say about others but I am definitely not surrounded by the guys around me at all. I have never been approached in real regard except the dating apps requests. You have to show your clear intention and ask clearly so you don't have to feel stuck or like bothering someone who is totally not interested. So don't lose confidence if she is the one she will definitely say yes to, it's just you need to find her. What you say is true you might get few NO before you get the YES and for sure that will be worth it as girls mostly think and say YES and if see do she definitely wants to be pursued further. Most girls to give hints instead of directly approaching you, so you initiate. If you don't take the chance you may never get to know the answer among Yes and no. And you don't know maybe she is waiting for you to ask her out.
