I had this problem for the past 10 months. I was sure something was wrong with me. Sometimes with my girlfriend I couldnt finish sex. I'm 24 and completely healthy.
Today ive masterbated 8 times and all 8 times my erections were rock hard and lasting. This morning I realized what my problem is and you might have the same one.
One night 10 months ago I lost my erection during sex. It flipped me out completely. Ever since then, ive never really had a complete erection until today. I found I had gotten into a cycle. Everytime i'd think about sex, i'd think about the time I lost my erection, thus making it impossible for me to even get one. Today I just stopped thinking about it and voila!
You're in your sexual prime and I doubt you have anything physical going on with you. I've talked to my buddies about this alot man and it seems sometimes alot of guys have this problem for some period of time.
When was the first time you noticed this, and are you stressed out and anxious alot? These things impact your sexual state incredibly. No matter how hot you think a girl is and no matter how bad you want to have sex, if you are even remotely thinking about anything that has to do with erections problems, you won't be able to function normally, if at all.
I was so worried after 10 months of having issues with this, and my relationship with my girlfeind literaly ending. I was constantly depressed about it and was going to see a doctor soon. Turns out it's all mental in my case, and i'd bet my life its the same for you. Give me some idea of whats going on in your life, school, girls, depression, guilt..???
