It absolutely sucks that we weren't born male-bodied and therefore can't make our own T. I have strong feelings about it, but they don't translate to resentment of the medical profession -- it's the hand life dealt me.
If I were a Type I diabetic, I'd hate it, but I wouldn't resent doctors because I needed to take insulin and have my health status monitored. Not being able to manufacture T is pretty much like that: it's a medical condition, and treating it requires fairly close medical supervision, especially for someone my age. It has the potential to interact with other meds I take, and my age makes me more at risk for some of the potential problems it can cause, like raising cholesterol and screwing with my liver. I'd rather not have to get my blood tested every few months for the rest of my life, but if that's the price I pay for being a healthy guy, I'm OK with it.
It doesn't feel to me as if my doctor is "an outside party controlling my testosterone level." Maybe I'm just lucky, but so far, at least, she's treated me like a partner in making decisions about my dosage. That said, I do tend to listen to her advice.
And it may not be addictive, but T is very much a drug of abuse. There's a huge black market, and it's particularly alarming that T and the synthetic steroids are increasingly abused by teenagers, who at a high risk of dangerous consequences. (Keep in mind that abusers may be taking many, many times a therapeutic dose). So, yeah, I get that it's a controlled substance.
