... have you had unprotected sex?
some discharge can be normal... but discharge is usually a sign of infection. If you've had unprotected sex then you have a reason to be concerned of an STD such as gono, chlamydia, NGU which could cause the discharge. You also would have been at risk for other stds such as syphilis, hsv, HIV and you would want to consider a full STD panel
It sounds like it might be just a bad reaction to the lube or maybe bacteria. See a Dr.
