Everybody always says there's a bunch of negative effects associated with masturbation but no one ever posts any studies. It's all baseless claims and spiritual/religious mumbo jumbo. I don't think there's any problem as long as you don't end up getting into super degenerate and harmful shit.
I personally wish I had it in me to masturbate more, my porn game backlog keeps getting bigger but I only really get the drive to coom every couple of days.
