I am a 15 year old male, i need help because i am getting really worried. Lately, when i masturbate, my penis doesn't feel erect and it doesn't feel normal to when i am usually masterbating. it feels softer, and i have had less of a drive, in order to get a semi-erection i have to physically do it myself with my hands, rather than it coming on its won. i am sick with a bad cold, but i'm not sure if that has anything to do with it. i just masturbated by rubbing my gentials against a bed, i know it sounds a bit wierd or funny, but sometimes i use my hands. i was able to ejaculate but as soon as i ejaculated my erection went down suddenly. please help me i am scared and don't know what to do .
