I'm guessing you're asking why your vagina becomes wet, the question didn't have that part. lol. But anyway, there are a few reasons it could become wet. You could think the guy is hot, you could be sexually attracted to him and his penis, or you could be horny aka you want sex. The reason you pick is up to you and what was happening at that specific time, but its most likely that you're sexually attracted to him or you're horny. It's pratically the same type of response for a girl that it is for a guy getting an erection.
