Weak erections for masturbation by not for sex?

[Guy31]

After not being able to have good erections for a long time, I got my ‘mojo’ or whatever back (not sure how). My erections were getting better over time and I recently dated a girl who kinda helped me get my confidence back despite never actually being unable to get it up while we were together. The more we had sex, the better my stamina was in the sac. Now it’s over and I noticed before masturbation never gotnke that hard but it still doesn’t, and I don’t want to go back to those ED days. Porn gets it up, but not fully. Imagination wth no visuals is nrealy pointless unless I really try. I’m taking L arginine and trying to improve my EQ as much as possible since I’m not as sexually active but is it weird I’d only b like 70%? Most guys get rewired for just porn but even when I couldn’t get hard porn never really helped too much. Failure to launch is still a fear and insecurity for me. I’m happy to have confidence with a girl, I just don’t want to lose it.
