I'm super weird about this stuff. Not that I pretend it doesn't happen, but I get embarrassed. It's one of the only things that embarrass me so I will avoid it at all costs. However, there have been some very strange moments where I've gotten freak wild hairs and managed to work up the nerve to do it and laugh, but it was still embarrassing. Since it's usually not noticeable, I might do it every once in a while, but only when I'm 100% sure he cannot notice it. Lol. Other wise I hold it or wait until I'm alone!
We have been together 5 years and I'm still embarrassed by it. He rarely does it in front of me too, but has before. I guess we're just shy about that and we try to keep bathroom stuff out of sight. Lol.
