I'm 18 years old with some form of erectile dysfunction. I've had multiple girlfriends over the past year and the whole timed I've only been able to have sex twice. It gets really depressing when I look at older guys in their 60s who've been on Viagra for years and it stops working, it makes me wonder if I will be permanently impotent by my 30s. I saw a doctor about it last year, but the only thing she recommended was seeing a therapist with my partner who I'm no longer with. This kind of stuff really makes me wonder at the quality if life in the future especially since so many older guys really struggle with this, but I experience it so young
