When the time is right, it will come. Just continue with your life, if you having sex have safe sex.
Hi, you will get a wet dream one day, but dont let it worry you and you will know when you do, its not down to filling horny or looking at dirty pictures, its all down to you dreaming of having sex with a girl/women, could be a aunty or your mums best friend, even a film star, but when it happens you will know.
Good Luck
