I'm a seventeen year old virgin and I was getting in the shower and looked down and my nipple looked wet so out of curiosity I squeezed and a whitish clear liquid came out. I'm freaking out. What is this?!? I keep squeezing and now my breast hurt I just don't know what to-do.
Unless you have been stimulating the breast for lactation or on medication which can induce lactation - this indeed is a cause for concern. Stop squeezing your breast, you may hurt yourself. Meanwhile go see a doctor
