I am 23 M , and not sure if I have ED or not. So , last year I had sex for the first time, with my bumble match , and while wearing condom, i was facing difficulties, to keep it erect . There were time when I would get rock hard erections but then lose them.I guess i was able to keep it erect for like 5 minutes top while penetration.And last month I had my second encounter, pretty much the same on first day , unable to keep it hard . But coming 2 days , i was able to get and keep it erected for like 6 out of 10 times . But for first minute or two , it would get super hard , but then like 70% of its maximum capacity.(i hope it makes sense) . And at 2 instances i did it for more than 10 minutes i guess. So little background about me , I am 5’10 , goes to gym 6 times a week , did my full body checkup, and my testosterone were 640 , sugar levels were fine , thyroid fine, cholesterol level in control. And also one more thing, i used to masturbate a lot , like 2 times a day , everyday, while watching porn . And while masturbating, if i loose my interest, I would loose erections . And i get hard morning woods. And also , I noticed, breathing technique, and kissing really helped me keeping it hard. This is really affe me. So what could be the reason behind it. I am really nervous.
