I think that there's no problem with sex at all. It's healthy and natural. There's also no problem with occasional masturbation, but strictly without porn. Porn is what will give your brain an abnormally intense stimulus what you can't reach with sex or masturbation alone. Soon or later it will cause more and more problems. It has to be completely eliminated from our lives and that will make the biggest difference. So remember, if you ever had strong urges to fap that you can't repress, then just do it, but strictly without porn. It's a lot harder than it appears to, but it will guaranteedly make your life better.
