Do you and your partner use lube?

Soooo... I felt like when I was a little younger, I had no trouble self lubricating. I can never figure out if I'm struggling to do so because it slows down as you get older or if it's due to my birth control, depression, infection, etc. I don't think I've been completely wet all on my own more than a couple times since I was maybe 19 or 20. I'm only 24 now. So does anyone else use lube often? I've heard people make jokes about "dry vaginas" and I'm just self conscious that this is strictly a personal problem...
