I have had this issue for a while and it's bugging me a lot and affecting me psychologically and my self esteem. I have had a couple of issues regarding my "package".
A little bit of myself first: I'm an 18 y/o Asian male who's slightly underweight but otherwise in pretty normal health (I'm 5'7" in height and 50-55kg in mass). I have a high metabolism rate, which causes me to be constantly hungry every 3h or so, which also explains my skinny frame. I'm not sure whether it's because of low metabolism rate or low testerone level that is the reason why I am having trouble bulking up but that's not my main problem though.
I have lost some size to my penis length. I may not be particularly well-endowed to begin with but I remember my penis size used to be perhaps 4-4.5 inches (give or take?) when erect. However, over the years, I slowly realised it had seem to shrunk by some length. Currently my penile size is about 2 inches when flaccid and about 3.5 inches when erect. Is there a reason why my penis size has shrunk?? For the record, I'm still a virgin and I have never masturbated before in my life. Okay, the latter sounds kinda weird to some of you but I just never had the urge to fap before in my life. Heck, I've never heard of the term masturbation until when I was about 11 or 12 during a sex education class and it wasn't until when I'm 14 or 15 did I really knew the action involving it (I previously thought it involves rubbing the penis using both of your hands, similarly to how you start a fire by rubbing wood lol). Although my size has been a concern, I have read many articles online that there are still many ways to still be good in bed despite having a "small tool" (foreplay, oral sex etc). I'm just a little afraid however, that my tool may shrink some more to the point of micro level.
My next issue however is much more worrying. Over the years, due to some personal issues that had happened in my life, I had very much became a very changed person. One of it was I started to lose my desire for sex, to the point where I can say my sex drive is pretty low now. Even though I don't fap, my body still finds a way to release via wet dreams. However lately, I feel that my sperm bank has been depleting. I can get wet dreams without the sperm getting discharged (I get a wet patch in my underwear instead). Moreover, my erections these days dosen't seem to last more than a min and it has gotten less strong and persisting too. I rarely even wake up with a morning wood these days. What has happened to me? Is this a cause of ED despite my young age??
I don't know what has happened to me... I am afraid of seeing a doctor or even telling my family about this. Does all of these has something to do because of my asexualish nature or because of the fact I have never fap before or simply because I might have low levels of testerone? I'm really hoping it's a psychological rather than a mental issue. I'm a little afraid that on the day when I eventually lose my virginity, my tool would not be able to function....
Just because i don't want to use it does not mean I want to lose it...
