Hi there, thank you for posting your question on Ehealthforum. This is not intended as a substitute to visiting your own doctor.
I would not get too worried about this. It is, as you suggest, probably a temporary problem. Reduce your level of masturbation and do not worry about the quality of your erection for the moment. Looking at yourself or wondering about your erection is the commonest and quickest way of getting temporary ED in men in your age group.
