Penis :: Circumcision? Better Erections?

So, I went to see my urologist last month and he noticed that my foreskin became tighter. It has always been tight, since I was born, and I'm incapable of retracting it when erect. Whilst flaccid, I don't have any problem. But he said that, sooner or later, I won't even be able to do it at all.

I'm not afraid of the operation. In fact, I think it will be for the best.

What I want to ask is about the outcome of getting my foreskin removed. Until now, with my glans covered, sexual stimulation is practically null, whether vaginal or oral. My penis feels and looks almost like a finger, actually, and I'm not kidding. I was wondering if getting circumcised will indeed improve my sexual life.

Here are some issues regarding my penis that haunted me since forever:-

I'm generally scared of intimacy, because I'm so self-conscious about my penis: it looks kind of weird, strange, different from the other's, with that extra piece of skin. That makes me feel so very anxious, which commonly keeps me from having a full hard erection. (That's also where most of my performance anxiety in bed comes from).

Maybe getting rid of my foreskin will not only boost my confidence and self-esteem, but also help me to achieve faster, easier and harder erections: besides the psychological factors, there are plenty of nerve terminals in the penis' head, which remain inevitably unstimulated during sex due to the interference of the foreskin. Having the glans totally exposed, I guess, will make arousal not only possible but also more enjoyable. Correct me if I'm wrong.

People, I'll appreciate so much your input on this matter. It's so important to me to finally have a full and rich sexual life, just like it is for everyone else. In short: will circumcision boost my self-esteem and self-confidence (since I won't feel "deformed" anymore when naked), and will it contribute to feel more stimulation and, therefore, better erections?
