Suggest Treatment For Erectile Dysfunction

Recently, I've developed a new relationship with a woman which started off slowly in which she was comfortable lying down with me, kissing and snuggling but not allowing it to get sexually intimate. This went on for a couple of days, during which I experienced several uncomfortable instances of "blue balls" (for lack of a better term).

Later on, our relationship, eventually became intimate, but since those early days of sexual frustration my body has been experiencing what I can only describe as erectile dysfunction. I become aroused immediately but often sometime through the duration of foreplay I lose part of my erection, or often only achieve about 50% hardness, still able to climax, but nearly always making it difficult to penetrate.

I've never had this problem before. I almost feel like it's my body punishing me for "crying wolf", so to speak: to many false alarms. Or that I've damaged myself by sustaining arousal for long durations without resolutions.

Is there anything I can do to get my ED functional again without taking viagra, cialis or any other medication?
