Does your Female Frenchie constantly lick her vagina?

I have a Frenchie whose almost two years old. She always licked down there and I just assumed she’s cleaning herself but it seems like she’s been doing it alot more often. She will have times where she won’t last more than 3 minutes between licking sessions. It keeps us up at night and not only is the sound grotesque I’m worried she might have an issue. Anyone have any input on this? She’s not inflamed/swollen/red in that area. There’s no sign of an infection or anything. I honestly think she just really likes doing it and it’s disgusting.
