Wierd topic

Im 15 and have recently tried masturbating . I have tried doing it for 10 to 15 minutes straight and im just confused about why i still havnt cum or had an orgasm or anything like that. Can someone tell me what im doing wrong or what i can do to do these things because i feel like i would enjoy it way more if these things happened

Also i dont think i have ever gotton wet over something but i domt know because do you have to be wet everywhere around that area to say your wet or just inside
