Hard time getting wet

I’m 21 years old. I’ve been with my boyfriend for about 7 months now. I’ve been having a hard time getting wet. Yesterday we tried having sex, we even used a vibrator and I was completely dry. My vagina used to get wet on its own before by thinking of sex or when I was with different people.

I don’t know what to do. I feel so weird about it and idk who to talk to.
