Since you are getting normal morning erections, I'm thinking you equipt is not to blame. Could be you've just gotten too addicted to porn & continued masturbation for hours at a time. I would suggest cutting back somewhat on both the porn & masturbation frequency. Try to cut back to a few times a week, or at least no more then once a day. And from time to time, try masturbating with no porn stimulation - it can easily be done when you're horny enough. It's well-known that the continued visual stimulation of porn viewing tends to cause the user to require more & more stimulation to get any kind of response. Try to let your own body dictate how often you masturbate or have sex. Some of us do tend to get somewhat addicted to the whole thing & that just usually leads to all kinds of problems. I don't advise no sex or masturbation at all, just let your body find its natural 'rhythm', so to speak. You'll know you're there when you're getting sexual thoughts & erections just seem to pop up on their own. Hope this helps...
