19 and wet

Female here, age 19ok, i won't lie, like whats up with me or happening with me, everyday i get wet down there, would not mind if i was thinking of sex etc. etc. but the matter of the fact is that i am not, I am not thinking about sex, I could be walking and suddenly i feel nice and wet there, Its actually pretty annoying, even in a meeting i suddenly get wet.Is that normal??
