Nearing the end of fun?

[Sephtyan]

I'm 17. Just turned, in fact, and I've noticed that my libido is decreasing. This is certainly something I'd very much like to avoid. Nights are often boring, and I find it difficult to get to sleep without something tire me out... if you know what I mean.
I've researched what can strengthen or weaken a man's sex drive. I know that it is pretty much solely linked to the Testosterone levels, which are needed for muscle and sperm production. I've tried diets that will help increase my testosterone levels. Sadly, this led me to some very heated fights with the porcelain throne.
I'm wondering if anybody else has noticed or experienced the same phenomenon, and has found some way to beat it.
Thanks! :3

I felt that way but im younger then you. When I was 13 I was kinda horny, well very horny. Then I lost it, for like 4 months y libido was completely gone! But after a few months, it was back!!!! Just give it time

Intense exercise (not walking!) for at least 30 mins a day should help.

Vigorous exercise helps but you'll probably just have to give it some time and it'll return
