Not really , you can overcome your shy behavior , and introverts I think is the term for people who like being alone not that they are incapable of being social they just prefer loneliness.The most important thing not one ever mentioned yet: you don't have to be shy and introvert.
Look I know someone your age he is autistic he gets money from government for his disability he spends it on hookers I tried with him all sorts of arguments to convince him to be better I guess men your age just adopt a mindset and strike their roots deep in it where its iimpossible to pull them out.
Personally guys I think people like AGL are too stuck in this mindset that its no longer possible to change.
