Vaginal dryness.

My boyfriend and I been together for about three years, we have sex probably about 4 times a week maybe more. Well when we first start having sex, i use to get really really wet. Now we have start using lube because i don’t get wet enough anymore. Well he never said anything but i can feel it. I love him to death, i drink plenty of water & eat healthy. I told him to foreplay more but i still feel like I’m dry. What are some other things i can do to fix vaginal dryness. I’m only 22 so i feel like i shouldn’t be experiencing this feeling this young🤷🏻‍♀️ have y’all took any pills or anything?
