Queefing!

Okay so I have been having sex with my boyfriend for about 2 months now, but almost everyday. I have never queefed before until the other night and I made it super awkward!!:( but he just laughed and said it was normal. i know it's normal but ive never queefed before and all those times I've had sex before I haven't either. I don't know why all of the sudden I'm starting too, what does this mean!!
