Can’t get wet

I’ve been with my boyfriend for three years and our sex life has been great, but lately I can’t seem to get wet. He used to ask if I would mind using a little lube to make things easier, now I just get it out. Doesn’t matter how much foreplay we do or what time of day, I just stay dry.

Anyone else ever have this problem? No changes in diet, meds or birth control, so I’m at a loss.
