Gas attack!!!

I like this boy, and I can never seem to get him out of my head. often times I try to talk to him but every time I see him I get super nervous and begin to have massive gas. one time he was standing by his locker talking to some friends, I then decided that now would be the moment I finally approach him. I gathered all my courage walked right up to him, and right when he looked at me as I was standing before him, a toot escaped my bottom and left a bit of a foul stench. it was pretty clear I was the one to blame for this gastastrafy! so can someone please help and give me some advice? I would deeply appreciate it.
