Yes, you are a little. But you are entitled to your feelings either way, and it sounds like he is overreacting too. My husb is also EXTREMELY gassy, due to a medical problem. But I find it ok, for two reasons.
1) I made it clear from the start that it was natural and healthy and I would never judge him for it, obviously in exchange for the same from him. Also, it would be a non-issue for our family, meaning no negative comments, but no over-the-top celebration either. It is like a cough, you may say "bless you" but no one is clapping or carrying on. This has fostered a healthy outlook for our daughter too, for when she is feeling under the weather dietarily.
2) My husb is GORGEOUS! Drop dead hot, he could be a model and women claw all over him. So truly nothing he does is disgusting once I look at him. Maybe you could motivate/shame (lol) your husband to be more physically attractive and in shape (perhaps even together)? It sure makes their flaws easier to stomach. :-)
