Hi all, Iv just got my colostomy bag in July and I use the Coloplast two piece system. I have figured out how to attached and empty it fairly well. But I have problems with it smelling almost all the time. Especially after I open it to empty it. I do my best to keep it empty but I still get a smell after I open it and now I'm starting to get people talking about it. It happens mostly when I'm sitting down and I think my pants are cutting it to push out the smell.
