Nothing to worry about, guys. My voice crackled and was rough for about a month, then around the 1 1/2 or 2 month mark it just dropped. It's still dropping now, 11 months in, still refining. First thing I noticed on T was my facial hair thickening and coming in in more places. By the 3rd month, I had good sideburns, and the hair on my chin and upper lip was a lot thicker... it took until month 4 for it to come in almost throughout my face. However, everything takes time. I'm still waiting for my beard to connect to my mustache lol... it just keeps inching toward it, but isn't quite there yet.
Sex drive, in my experience, refines itself as well. I've been on and off T twice, am back on for the 3rd time now, and noticed that my sex drive went way up within 2 weeks back on T, but orgasms were really hard to achieve and really not too good. Multiples, which I used to be able to get pretty easily, were impossible. But after about 2 1/2 months back on, I'm now able to get multiples again, and they're pretty darned intense... though still not as satisfying. I seem to recall the satisfaction does return in time, though.
So... don't worry. You're young. Just be patient.
