My point was not that it is impossible that such problems exist: my secondary hypogonadism was found when I was 22 (I'm almost 30 now), and it was suspected that it'd been going on for a long while. My point was only to say that particularly when blood markers aren't pointing at a direct problem (eg in my case, a T level in the 30s and severe anemia), TRT should be considered one of several possible ways to address a given issue and probably not the first one. Fact is, you're at an age where a lot of changes can happen that may have chemical foundations or may not. Just seems to make logical sense to approach it as if they may not before deciding that it is chemical and aggressively pursuing that route. And I'm not saying you need to talk to yourself--I'm saying that considering a psychological consult isn't a bad idea before seeing an endo with the types of symptoms most of the people in their teens and early 20s on this board describe.
Talking about the volume or viscosity of one's ejaculate sounds like something that is probably assessed by most in a highly unscientific way, and regarding things like psychological evaluations, I'm simply saying that exploring that possibility is probably a good idea before deciding that you need to permanently take your body chemistry into your own hands.
