Pretty much every time I ejaculate it is a clearish color with very little or no white coloring, like (as far as I know) must guys that I see in porn videos which is usually a very pearly white color, and I don't think I've ever got that color. I read that it can be caused by low sperm count, which can be caused by excessive masturbation; I masturbate 1-3 times a day usually, but I didn't yesterday or the day before but I did today about 40 mins ago, and It was still pretty clear. And I want to have children in the future ._. I also noticed that I don't release that much seamen when I do ejaculate (again compared to male pornstars).
Don't masturbate for a week (if you can :lol and see if there's any difference. And for a gay guy wanting to have children (which I assume you mean of your own gene) you'd either have to directly impregnate a woman (ewww, vaginas ) or go through a surrogate mother using artificial insemination (in vitro) and your sperm count shouldn't really matter as much in this case. As for the amount of semen, porn stars aren't exactly the best way to judge your load. Try stop and go technique and you should shoot a nice amount.
I wouldnt compare amounts to pornstars... colour perhaps. Mine varies.. sometimes it's super-gluggy and white , sometimes its clear. usually a mix. Not sure if there is anything to be worried about, but I dont think so.
You're only 16. The more noticeable whiteness may come with time. With that said... It could be your diet. I don't think this is an issue for now.
The reason for the thin consistency and the small volume is the number of times per day that you're ejaculating. The majority of the content of semen is clear glandular fluid. With each progressive ejaculation, the fluid proportion increases and the volume decreases.
