Almost a man now: At your age, you're going to have some expression of mucin when you get an erection during the day, whatever you do when alone. Unless you shower more than once daily, you'll also have some of the odor of an unwashed grown man due to more sebum and keratin and bacteria for which semen / mucin are growth factors. Have you talked with dad? Your personal physician? Read a good book on growing up?
