It is completely normal to be very wet. I have noticed this too. Whenever I get really wet, I can't seem to 'feel' as much. This is probably because friction can feel really good, and if you're really wet then friction is out the window! I think the wetness is just a natural vaginal lubrication that your body secretes whenever it's excited. This lubrication keeps the vagina smooth, so that during intercourse, nothing gets torn or damaged.

It's not a bad thing, just try to apply more pressure, going faster, sometimes going slower too. It might also help to use items with a different texture then fingertips. I suggest having him finger you through clothing. Especially once I'm really wet, it feels amazing! There are lots of girls out there that have a hard time not getting wet enough, so while it's annoying, you're blessed! Good luck girl!
