Can't FART in front of my husband

We've been married for almost 2 years, together for 5.. I just can't do it.

He farts all the time.. he's like a man child about it too, giggling and shit.

But I just can't.

And he makes me feel so BAD when I do. Like I accidentally let out a little toot in the bathroom, and he makes this BIG DEAL about it... laughing his ass off for SO LONG after the fact....

It makes me so self conscience, I don't feel like I can even go to the bathroom when he's around anymore...

Help?
