I [19F] don't typically masturbate, but in the past year (since I've gotten sexually active) I've noticed at the 2-3 week mark since I've last masturbated that I get grouchy, depressed, and have a hard time staying emotionally stable. The general up and downs continue until I next masturbate or have sex (typically masturbation since I'm in a LDR), then I'm good for another 2-3 weeks. Does this happen to anybody else? Is it normal? And can somebody possibly explain why it occurs?

Edit: good God, I didn't know you all would like this question so much. I get it, few of you have gone 3 weeks without masturbating and nobody is mentally stable in this subreddit :) . Please. I'm waving the white flag. My poor inbox.
