There is nothing wrong with you at 13 if you're only getting erections occasionally. I always thought masturbating to orgasm wasn't something you should do. I'm struggling to get back in touch with myself, and I need to learn to relax again and know no one is gonna catch me, which I seem to be unable to do. I masturbate 8 or 9 times a week. Most males your age masturbate daily. There is no reason to tell your parents or to fear them catching you.
But if you're not having symptoms of prostate trouble which usually manifests itself at your age as random pain in your genitals then I don't see a problem with your binge and break cycle. I suggest you insert a table which consists of age group and the recommended frequency of masturbation. If you think I would be better off asking my doctor, what would I even say? I had been touching myself on and off. It features a smooth outer coating made from durable silicon, but inside the mechanism is where the magic happens.
Not all boys have that happen, and for most who do, it lasts less than a year. You can't "will" yourself to have an erection. I had my first orgasm today. I'm 17 and I masturbate every day. You are young and might not be ejaculating for a year or two. I want to do so because I read here that its bad.
I would suggest finding an online support group for your condition and asking the members there what they do. You seem much too young for that. I usually wear shorts or sweats but even with jeans, my erection is still noticeable. You should enjoy it and not try to stop. That is an atypical way of masturbating that will not help you be more sexually functional. I need to get rid of an infection. You never measured your semen volume accurately.
