Sometimes I wonder how many known people are on testosterone. It is pretty obvious that all bodybuilders use them (Sly, Arnold, etc) regardless of they admit it or not. Brittish singer Robbie Williams admitted he is on cypionate. I am sure its much much more than that. But you do not see these people coming out of closet and admitting it, even as a publicity stunt. And you cannot blame them.
This is partly what kills my spirit. I am open with my wife, she knows exactly what is going on. But I cannot share it with anyone else, even parents. What I am going to tell them? I lost sex drive and good part of orgasmic sensation? This is not something you discuss in the open, even with the close family.
I know my situation is a little different than most people in here due to the origin of my T issues, however, here is what I say if describing this to someone. I just say that I have some endocrine issues/hormonal imbalances that I'm dealing with. Nobody really questions the gory details when you say it like that. If they do, I just say that certain hormones such as DHEA, estrogen, testosterone, etc. are being normalized through medication and supplements. No one (except my close male friends) go into the details as to whether your penis tip is still sensitive or if you are still getting erect.
Incidentally, regarding celebrities...
Arnold has 1 testicle. Google that and you'll find out more about that. I would guess he's on some kind of TRT at this point. He probably damaged his system from earlier overuse of 'roids, especially as he's had heart surgery and broke his femur skiing...that is most difficult bone in the human body to break. He probably has some kind of osteopenia.
Lance Armstrong has 1 testicle and his body was immersed in radiation and chemo, and he was able to have 2 kids naturally (beyond his first 3 kids where his sperm was frozen). He was also a ladies man after going through all that. He's got to be on some kind of TRT in addition to other things after his body went through all that.
I think there's more people out there with issues than you would think.
