Dry...2 much sex? Pregnant?

In short...
Fiancé & I spent the weekend together. Had lots of sex. Think he purposely was trying to get me preggo. Day after he leaves, my vagina is dry. No pain or any crazy symptoms or odors but I'm just dry down below. Has this happened to anyone? Is there really a such thing as too much sex? Could dryness be a result of a hormonal change? Pregnant? I don't know what to think, this has never happened to me before!
