You will be more certain in time of your sexual identity. Only you will know how to label yourself correctly. I was thrilled the first time I saw someone wearing a pride pin and was able to get some information from her. The first time that I went to a gay group, it was, quite simply, a relief. Yes, you are absolutely normal.
Many people are gay.
Start by reading. If you feel comfortable doing so, ask the librarian in the Young Adult section of your public library. Librarians are usually glad to help. Moreover, librarians operate under a strict code of ethics and are legally obliged to guard the privacy of all patrons, including minors. If your public library does not have much on sexuality, the reference librarian can request good books and journal articles through interlibrary loan.
