Creamy Vaginal Discharge (during intercourse)

Hello, My question is about this thicker substance that happened today during sex. My guy decided to wake me up with some morning time action. It was very slow, and I guess we don't go too slow or long often.. It really took me by surprise when what looked like a white lotion was on me and the bed. I was pretty freaked out, and went on to investigate. (To my guys disappointment) This was the first time I noticed it. And all I could think about was lotion, coconut crème (which I wished I had had the night before at dinner), what I have previously read online, and confusion. Typically the fluid I excrete is clear..The smell was not super noticeable-in fact almost non existent, but had a hint of sweet. FYI My guy and I are fairly sexually active. Recently-a few days ago, we must have gone too crazy..and I have felt tender and bruised a bit. My lower abdomen area this morning and mixture of late the night before has been feeling a little burning sensation. Like maybe I will start my period soon. I originally passed it off for eating super spicy food and drinking a small amount. Now that the next morning has come and the sensation has not left.. I am slightly worried about the possibility of infection. I did reading about this previously, and just was looking for a little customized input. Has this happened to anyone else? (Secondary question: Where/when does the burning occur for things like BV?) Thank you!
