I have white creamy sticky mucus coming out of my private part what does this mean? no smell but is itchy sometimes. only happens when having sex.

Ah, The Price We Pay: Uh, pardon me for asking, but is this unprotected sex? If so, then maybe it's the remains of your partner's, how you say, well, you know what I mean. If not, then maybe it's due to any jelly or lubricant you use, or sensitivity to a condom, or sex toy, or sweat or from the activity itself or maybe a yeast infection or some other sensitivity. Maybe you should get yourself examined by a gynecologist
