I'm 23 and it's really only the past 6 months that I've started taking this "self improvement and get laid" thing super seriously.

I'm a horndog right now but don't have alot of girls to use it on because I didn't self improve these past few years and take getting laid seriously.

My worry is that as I get into my mid/late 20s/ 30s my testosterone and libido will drop and even if I get alot of chicks it won't be as fun as it would if I was getting laid regularly in my early 20s. Is this true or no?
