Is it normal to masturbate at brother's wedding?

So, this afternoon, I was the best man at my brother's wedding and I was sitting in the second row to the front in the church. He was very excited, he really loves this girl.

Anyway, as they were walking down the aisle, I saw her nicely-formed ass, and I felt immediately compelled to masturbate. Nobody noticed at first, because I started off slowly.

Suspicion was aroused when I was called to bring the rings, which I had worn on my fingers to keep them safe. A few seconds later, I had a wonderful, spectacular orgasm, and I came all over the rings. The church was silent, shocked at this utter spectacle.

But I got up and placed the ring on the bride's finger and she began weeping and she ran back down the aisle in tears.

Now my brother is mad at me because she thinks his family is messed up and the wedding is off.

But I have felt compelled to masturbate in public before, usually when women bend over to pick things up.

I'm just over-horny.

Is this normal?
