As long as it isn’t interfering with your life, flick that bean. It’s not hurting anyone.

You don’t need to compare yourself to others. They’re not you. Twice a day doesn’t sound excessive to me. 20 times a day might, but twice? It’s your body.

Also keep in mind female masturbation has, until recently, been discouraged by western culture as deviant. It may be that some of your friends are downplaying their own regularity for social pressure (you already mentioned you vocally agree with what they say – others are probably doing that, too).

I do it every month or so for the dopamine, but I’m asexual. I’d say even a few times every day is fine. If you think it’s disruptive to your life, I’d recommend therapy, but that’s like if you can’t focus in a meeting because you haven’t done it for an hour and that’s all you can think about. Otherwise, just enjoy yourself. You’re fine.
