Hi, thanks for using healthcare magic Based on your description, it sounds like a condition called peyronie s disease. In this condition there is curvature of the penis that can be worse during intercourse. It is associated with fibrous tissue ( which is scar tissue and likely are the lumps that you are describing). This condition is treated by medication or surgery. Surgery is considered only after medication is used. The most common medications used are vitamin E, cochicine. Other medications are verapamil and interferon. Some persons also inject the plaques. You should consider visiting your urologist I hope this helps
