<s>[INST] I m a sickle cell anemic patient. I ve been living very fine cos I ve been receiving utmost care coupled with good nutrition and I drink water a lot. I was researching on the effects of too much bilirubin in the body when I came across the word priapism . I was shocked as I used to think those unwanted erections I had were normal. But after conducting more research on priapism, it doesn t completely fit my situation. It s slightly painful, never lasts for up to an hour, I doubt even half an hour. It actually added to my masturbation habit that I m trying to get rid off now as that seemed to be the only solution to make it die down, even after ejaculation it still stays slightly erect for a few minutes. Whenever I sleep off or get absorbed into another activity, I wouldn t even know when it died down. I just want to know if I have anything to worry about. I m just 18 years of age. [/INST] Good Day and thank you for being with Healthcare Magic! You are very prone to priapism which is defined as unwanted erection lasting for more than 1-2 hours. If ever you have that symptom I would suggest going to the emergency room to relieve the erection. Priapism may cause structural damage to the penis if left untreated. For now remain vigilant and erections for 30 minutes without pain is normal. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at:   I would gladly help you.  Best wishes </s>
