I had head injury 5 days back. I was unconscious and was hospitalized for 1 and half days. I am completely fine as per doctors. I was put on catheter in my penis. For couple of hours until I was regain my consciousness. Its been around 5 days now. Will that catheter have any effect on my erection? I am anti biotic and I do not have that much of pain while urinating. Its like I do not have any uncomfortableness right now in my penis. I am getting erections whenever I am wanting but still I am anxious whether the catheter will cause any harm for my firm erections? And can I masturbate or engage in sexual intercourse with my partner recently? I am 22 years of age.
