Weak/Not often erections
How's it going, idk how else to start but anyway.
I'm a 21 y/o male, and I have a girlfriend. My sex life has always been something I've taken pride in, really just because I enjoy satisfying my partner. Recently (kind of as of last year maybe the middle of 2025) my erections haven't been as full or as strong as they used to be when I was younger (in high school).
Won't sugarcoat it though I've looked at some sort of pornographic material and I used to never have an issue being hard or staying hard before, during, or even after masturbating or sex but recently I don't know what's changed at least since last year. There would be times I would be with previous partners, and we'd have to stop because they couldn't keep going and I wouldn't finish or I would and would be able to keep going anyway. Regardless of that it's always been something me and them would talk about and make sure everything was okay (mentally and physically wise).
I guess my main concern is if something is wrong with me, I wasn't a "fit" guy either, I used to be 250+ pounds at 6'1, would rarely workout and slept and ate like I had nothing else to do. As of now, I'm out of the military and stay pretty active, lifting at least 5-6 times a week and get my cardio in daily. sleep is here and there with how many hours studies say we should get. I want to say that around the time I realized my erections were at their peak was before I knew about certain supplements like zinc, l arginine, lecithin granules and maybe one or two other things I used to take and I did notice a change but I didn't take them as much after a while and still felt the fullness that I used to have. I haven't taken anything like it for about two-ish years, and it has been a concerning amount of time since my last rock-hard erection. I'm not as adamant about it now as I used to be just because sex isn't something I'm truly concerned with but I'd like to be able to feel myself when I wake up in the morning or randomly get a boner like I used to and feel somewhat uncomfortable in my own clothes. (And I mean that in the most non-weird way as I possibly can.)
Advice is definitely wanted.
