i'm only 19 and i don't get very "wet" either..
obviously you need to use lubes... but i would focus on your diet.
what are you eating??
do you eat a lot of salty food?
this may not even be logical... but i eat too much salty food, which makes your body retain more water.
are you drinking a lot of water????
my advice would be to try drinking lots of water, then perhaps you can produce more... personal lubricant.
