Can rough masturbation cause weak erections if i give it time will it be back to normal ?

Here are some ...: Rough masturbation itself would not weaken erection, but may cause penile fracture-but rare. "too-often" masturbation may induce weak softer erection while trying sex before fully recovering after an orgasm/ejaculation; such situations suggest: mental desire has overrun what physical ability can offer. So, slow down the frequency of masturbation and do it after a full recovery - refractory period.
