30 something woman here, apparently I masturbate a lot compared to my friends.
I have to say “yeah once a week too” when they raise the subject ,when in fact it is multiple times a day. Husband would also do 2 times a day if he kept to his “normal” cadence. I know “whatever works for me” is right, but I’d like to compare to other people my age that aren’t my friends.
I don’t think “normal” is a helpful frame of mind here. Maybe “healthy” is a better way to see it : does it make you feel good ? Does it feel like a healthy part of your life ? I don’t want to decide for you, but from your other comments it seems like it probably is.
I would call it a problem if it becomes an obsession, if it takes time away from other things you want to do, if you do it so much you hurt yourself… Etc.
