for a period time of doing some stretching but daily jelqing i stopped for one day and the next day i woke up with a raging erection. my dick was so hard that it i was in a lot of fuckin pain..and from then on, now it seems if i cum one day the very next day in the mornin i get it again and then 2 more days after. if i go for a month without cumming then it doesn't happen. these erections last for a very long time and hurts like hell. what can i do to help to stop it from happening or just bringin my erection down.
