Discharge : Discharge can be normal depending on where you are in your cycle (heaviest right before your period). On the other hand it could me a sign of a bacterial or vaginal infection, or even a sign of an std like gonorrhea or chlamydia. The best thing to do in your situation is to have an evaluation by your primary care provider or gynecologist. Good luck.

Sexual lubrication: The non odorous clear vaginal discharge is actually lubrication as a result of sexual arousal and is normal. It is Mother Natures's way of preparing the genitals to "receive a visitor".
