I am 15 years old and I have been suffering with some problems recently. i have noticed that my sex drive has decreased and I am struggling to get erections. I have a balanced diet, get enough sleep, not stresssed, and I do not smoke or take any drugs. I never get wet dreams and unlike when I was 13,14; my erections arent as hard as they used to be and normally I can only get ¾ of full erection but never actually a proper one, no matter whether I am trying to turn myself on or watching porn etc. I cannot think why this is. Now I am starting to get worried when I am with a girl I won’t be able to get up. I am not suffering from any condition like anxiety or despression and I am living a very stress free life, someone please help?! I am just worrried this will ruin things with a girl and that I will not be able to get up as I am struggling to alone, and other people say they sometimes get random erection and I never do, even had a girl basically twerk on me naked (i had trousers on) and I did not get hard just precum, please somebody give me some advice or help, what do I do?
