First of all, you should try to make changes. Although you don't say that you are talkative, you should at least talk comfortably with each other instead of ending up embarrassed every time. This is very important. Although boys who say stupid things may be cute sometimes, they will become really stupid after a long time!
Second, you should have your own unique skills, because you are quiet, so you have to be more talented than other boys to attract girls, such as being good at playing guitar and basketball, or getting good grades. Anyway, you should have a bright spot, if you don't talk, you will shine!
Third, be helpful and reliable. The more quiet and introverted people are, the more they need to feel safe. The message you want to convey to girls is: I just don't like to talk, but everything else is fine. If you are particularly reliable in everything, girls will think that you are not only safe, but also modest and don't exaggerate your efforts!
Fourth, quiet and introverted children might as well get along with other sociable boys and let them let you know more friends and get rid of social fears slowly! In fact, whether you know boys or girls, it will help to improve your social skills!
Finally, don't rush for success, because quiet boys generally attract quiet girls, and often these girls are slow and shy, so if you want them to find your bright spot, you should start with small things, express yourself slowly and get to know each other slowly!
