So I'm an 18 year old guy and I've never really been able to make myself ejaculate. I've had wet dreams and sometimes wake up when the wet dream ejaculation is happening and the liquid that comes out is always water and clear. When I "ejaculate" after masturbating what comes out almost always resembles urine; it's very watery and occasionally kind of yellow. Because I'm 18 this has me very worried as I have never been able to ejaculate regularly and I think that I should be able to do so by now.
