no, i understand why they have it, i just dont understand how they get itNot so many have it. You may feel the opposed way because people in relationship in middle school and highschool are very ostentatious with it, but that's pretty much all and most of the time, those are very shallow relationships.
As for how they got into a relationship, well, by talking to each others...
nevertheless, Just talk to others, don't be afraid to talk to girls and, with time, you will end up in a relationship without even realizing, if not in your teens (no worries, it's normal, especially for a boy), then later.
