Semen usually spurts out when you have an orgasm, that excited feeling at the end of masturbation. Semen also can leak out in small amounts when you have an erection. Or it can come out during the night if you have a "wet dream". Semen is usually only two or three teaspoonsful, and will often have dried up by the morning. Dried semen has no smell. If you are a teenager, urine will usually never leak out, unless you are maybe still wetting the bed at night. Urine has a distinctive smell, which you probably know, even after it has dried. If urine is leaking out you should tell your doctor, as this is unusual with young people.
