i suggest you seek immediate medical attention. it sounds like you're describing priapism which is a prolonged erection not caused by sexual stimulation. in priapism blood gets trapped within the penis causing it to remain erect. if this isn't treated quickly it can cause permanent damage. you may have heard this on commercials but. if you ever experience an erection lasting longer than 4 hours seek medical attention. this condition does not result only from the use of drugs for erectile dysfunction. it can occur in any healthy man. take care!
i have a harden penis that dosen't reduce
