Drying up (. Very specific)

Trinity

So recent when me and my bf get intimate I get very wet like seeping thru my panties wet but he starting fingering me I enjoy it a lot but I enjoy it but I start to dry up after like three minutes. I the problem isn’t that I’m not enjoying it bc it causes me to orgasm every time we do it

Someone please tell me I’m not the only girl that does or has does this
