Hey, bro. What I've found over the years is that if you go looking for something wrong you'll usually find it. That's not to dismiss what you're doing and certainly not how you're feeling. But, we can keep searching for that "magic" pill, that one determinative test, that will finally set us to boner-dom, but I found this is an illusive dream. I'm over 60 and obviously I have less testosterone than you. I have been overweight my entire adult life (fat is bad for the hormones) and mostly out of shape...I'm a real catch, in other words. Anyway, I can still get a boner and cum PIV. I don't get as riled up as I used to and I would say my erections are not as strong as even in my 50's, but the pork sword still works. Of course, we're all different, but I found the most important organ is between our ears. When I was all nicey nicey with the wifey the only way I could cum is if she beat me off. Sometimes I'd go soft in her hand, she'd complain about a sore arm because it was taking me so long, and my only way out was looking at P. Being nice, considerate, kind, deferential to our woman's needs is, imo, a chump's game. I got my mojo back by behaving like a caveman. Think of it this way: when you're a teen you try things like booze, pot, piercings, hair cuts, etc, to find out who you are and where you fit. The kids who don't try those things end up, usually, acting out in their 40's, like I did, and start cheating and other shit. What I'm saying is "we" are powered-down because we haven't practiced being powered-up! A pattern started when we were young. It wasn't just P that ruined our boners, it was being forced (due to childhood circumstances) to hide who we were. Because of this we meet and end up with people who enable us being powered-down, because that's what we know and are comfortable with. We keep trying to change, but it is like trying changing the curtains in a prison cell. We're still in prison. Luckily, the prison door can be opened easily and it only takes a little bit of courage. Deep down you know what you have to do. There is no perfect diet, supplement, or exercise routine. Imo we must connect with our primal selves, even though to our previous selves this looks like the kind of ass wipe we've always hated. Things are always best for my penis when I feel like "me Tarzan, you Jane. Let's fuck!" The old me would have thought that person was a knuckle dragger, but because I didn't get to practice knuckle dragging when I was young, I became every woman's little bitch. You've got this!
