Thanks for the help fellas
It is no a dysfunction, nerves are completly normal. The first time me and my first girlfriend tried to do someting I was so nervous I couldn't. She would have let me do anything I wanted to her and the most I could do was take off her bra and touch her breasts. My hand would not go past her waist because it was shaking so much.
After we broke up I ran into her again about 5 of years later and we spoke about that night and it was a self confidence issue with me, because within 2 hours I was having sex with her because I had a lot of self confidence when I ran into her again due to the fact that I had other girlfriends since her and had sex since her.
One of the worst things about all these commercials for ED medications is they have everybody convinced that if they can't get an erection one time they have it.
ED is a physical problem caused by a decrease in bloodflow to the penis. That means that you have difficulty every time. Once in a while, especially in situations where we're tense, we can have difficulty getting an erection. This is not ED and is normal.
I assume that this was the first time the two of you had genital contact, which can be a scary thing. Even older guys who have had a lot of partners sometimes experience this with a new partner. "What is she going to think about my penis? Too small? Too big?"
As your relationship progresses you should grow more comfortable with each other and it shouldn't be a problem.
Doesn't sound at all unusual or "dysfunctional" to me. I think you have it classified correctly as you tagged your post with "anxiety" and "nervousness". You'll get over it.
Stick with her and you'll both be ready soon enough.
