Trouble making myself cum?

So I usually masturbate at least once a day, I usually do it at night. & I am usually super wet really quickly, & I can make myself cum really quickly & it's usually a really good orgasm. But the last couple days, I have not been getting/staying very wet, & j just can't make myself cum, or if I do cum, it's just ok.

Do other girls have this issue sometimes? Should I just take a break for a couple days or something?
