I've never had a girlfriend before but I'm trying to get one. At first, a lot of my guy friends were put off by me, found me annoying, weird, or stupid, at the beginning and we only became friends because I was pretty persistent at first.

Why is it so bad to be persistent and chase with girls? I don't see how there's any fundamental difference here. Why is that if a girl seems annoyed or disinterested with you, you should immediately give up and try another? If I did that while trying to make guy friends, I would barely have any close friends at all.
