Is it normal that i get wet when i pull my pants up to my waist?

Im a female who has noticed a pattern after performing one specific act. Whenever I pull my pants up to my waist (belly button/ navel), my pussy gets wet and tingly. I basically get horny. Of course this doesnt happen with all of my pants. Just the ones that actually reach my waist. But it happens every time I pull my pants up to my waist without fail. I have thought about it and then I said maybe its because its easier for the material to hug my vagina when my pants are pulled up onto my belly button. I dont give myself a massive camel toe or anything like that but my pants are just fitted on my pussy. I cant help but think that this may be the reason why some girls (including myself) wear their pants high up there.
