I’m 18 years old, 6’1” with a slim/average build, used to play football 4 times a week but have stopped this recently, I walk 30 minutes to and from work every weekday. 3 weeks ago I was with this girl, just occasional kisses and hugging that’s it, but I achieved an erection in this time. Last weekend we met again, this time it led to sex, however the best I could achieve was a semi (exactly the same as an erection, but just wasn’t hard at all) this then obviously led to nothing. I’ve been thinking since and can’t remember the last time I had an erection since the kissing (not that I keep a record, but this was a thing that came to mind) this could be my brain tricking me due to embarrassment or something I’m not too sure. I’ve kept a record the past few days and have not completed an erecting since. Do I actually have ED and what’s the best way I can go about curing this?
