Too scared

Is it just me that has a phobia of going for a poo in other people's houses? I'll go in my mothers and my best friends but I live with my boyfriend and I'm too nervous to go while his parents are here. I guess it's because they will point out that it stinks and make me feel small but I'd happy go if it's just my boyfriend home. It's getting ridiculous I've lived with him for 3 years and only gone about 10 times here.
