This is a bit embarrassing to talk about, but since this is an adult board, what the hell. Usually, when I masturbate, my penis usually goes flaccid in a matter of minutes after ejaculation. However, I just finished up a session and I'm still rigid. I'm not talking like a few minutes, but it's coming up on an hour now and my penis shows no signs of going flaccid. Is this common, or should I start getting worried? Off to check the web.
