I had sex with my girlfriend a month ago and couldn't get an erection. However, on that day, I had masturbated 9 hours before sex, slept only 2 hours and had walked for approximately 30-35 mins under the sun to reach my girlfriend's house (which might have dehydrated my body). I also want to include that I have been masturbating to porn since 5 years so porn, masturbation might be the problem for me. However, after that day, I quit porn and masturbation and after 4 weeks I have noticed the following results: 1. Frequent morning erections as compared to before. 2. I can achieve erection without looking at porn, just by touching the upper part of my body. 3. In the last month, i've gotten hard 7-8 times by just looking at a semi-nude pic of my girlfriend and 4-5 times by imagination about my girlfriend sexually. 4. My penis feels longer and heavier as compared to the times when I used to masturbate. It feels more "loaded" than before. So my question is simple: do I have erectile dysfunction or was the erection problem just due to events on that day? If I have erectile dysfunction, what do you think about my recovery looking at the points mentioned above? Am I recovered or is there still time?
