What Causes Wetness In Vaginal Area?

I had sex 2 days ago, my boyfriend said I was really wet when we did it. (Wetter than I usually am) this made the sex easier and more pleasurable for me. But since then i've been wet nonstop, i"m not even with him or aroused and i'm still wet! It's starting to annoy me and it's getting quite embarrasing too. Why am I so wet? Please help!
