I have to second this.
DISCLAIMER: I say this without judgement because I've had my ED issues on and off and it's been a pain to nail the exact cause, but I will say, having been on various forums for various hobbies I like, the hardcore bodybuilding forums are the only ones where there's constantly posts on ED and guys taking stacks of supplements before a girl comes over.
Among the "normal peasants" (lol), sex doesn't require that much thought. Girl comes over, you fool around and get it on. Seems like among the more serious bodybuilding crowd, sex is almost like a mini 24 hour contest-prep and if you don't peak right on time it's a flop (pun kinda intended). It shouldn't be like that!
I'm in the boat with ya'll so again, no judgement, but I think if we pinning cattle hormones and research liquids, we are essentially druggies, if we don't sugarcoat it. I'd say, if this is really important to you:
1. Take TRUE TRT (not this 1200-1500ng/dl crap that all these clinics are doing, high normal range 600-800). Estrogen should be at a normal range if you aren't pushing yourself above normal limits, but still keep an eye on it just in case.
2. Really focus on RBC/Hematocrit, blood pressure, resting heart rate (those last two have been a struggle for me)
3. CARDIO!!! Nothing to do with bodybuilding, everyone should be doing 20-40 minutes of moderately intense cardio seven days a week, don't think of it in bodybuilding terms, think of it in terms of brushing your teeth or showering, it's just something you do. The amount of bodybuilders I've seen do a swim or bike ride and they literally look like they are going to die, while their out of shape friends are perfectly fine, is cringe-worthy. True story, I worked for a dude who competed and looked incredible. Got some mountain bikes so he and his girlfriend could go riding, the guy made it around one block and was on the floor gasping for air, while the girlfriend who had never seen a gym in her life and ate whatever she wanted didn't even break a sweat (that's NOT right!).There's all these lame excuses "oh the muscle makes it harder to float, I'm fast twitch", no dude, the fact that you consider 20 minutes on a treadmill at 2.0mph a cardio workout is what's gassing you out. Let me put it this way, you know how we laugh at guys doing curls in the squat rack because they look like morons? Well the cardio guys are looking like that at us because (some) of us think an hour brisk-walk on a treadmill is a grueling cardio workout. I know it's not fun for some of us, but it's just gotta be done.
I'd say diet, but I do believe if you're strong as an ox and have elite endurance, you can slack a bit on diet (a BIT).
I've started to change things because it's just getting ridiculous. I'm not slacking on the weights, but I should put just as equal aggression into cardiovascular work. Low RBC/Hematocrit, heart rate below 60 (50 even better), 120/80 BP MAX. I think if some of us focused on meeting those goals as much as focus on adding 1/4 inch to our calves or 50lbs to our squat, we wouldn't have so many of these "i can't get it up" threads. And yes, that does mean laying off a lot of the stuff we take as well, at least the more damaging compounds.
I say this with love guys cause I'm no better, I've done some stupid shit and I've got a lot of fixing up to do, but at least for the younger guys, I don't want them going down the road that some of us older guys did (I literally remember back in like 1999, some bodybuilding forum that recommended eating gravy and heavy cream all day and avoiding walking around the house too much to not lose mass lol... don't do this)
