Sorry if this one is an awkward one, guys.
Basically, I had a hair on my penis head, and wanted to remove it just in case. It was a bit sticky (I have masturbated beforehand), so I tried to grab it with my nails instead. What I did instead, was pinch my meatus. It hurt for a few seconds, but the pain was completely gone. I decided to masturbate just to check if everything is ok. And everything was perfect. I am 15, and hope everything is fine. Could there possibly be some long-term effects to this at all? Any nerve damages, or possible erectile dysfunction in the future? And also, what if my penis sometimes sticks to my underwear after forget to wipe after masturbation? I usually just pull the underwear, and it does pinch for a bit, but the pinch goes away in a few secs, just like the sensation I had experienced recently. Any help is much appreciated. Thanks!
