Does anybody else experience this with masterbation?

I'm thirteen, so obviously not having sex, I do masterbate though, I just use my fingers for clitoral stimulation, I'll do it every night, helps me fall asleep and obviously feels amazing so a win win. But when I do it every night for a few days, when I orgasm it loses its feeling??

It still feels great, but it just doesn't feel as good so I have to stop for a few days?? Anyone else experience this??
