I didn't say I wasn't attracted to women because they shit. I'm only saying I would prefer to not be witness to it. Keyword being: prefer. Of course I'll be walking into a bathroom that has been previously fumed (one reason why I have ventilation in every bathroom). I'm not going to leave my girlfriend because of it. I'm only saying that everything that someone does that is unattractive to you, is of course going to affect the sex appeal - even just slightly.
And I don't mean forever, I just mean at that moment. Unless you're constantly doing something unappealing like farting at inappropriate places, like during a meal or nestled together on the couch. That would have to be a constant thing though to be detrimental to the relationship. Look at how many marriages or serious relationships can't even last 10 years. It's everything you do that affects that. From the gagging sound you make when you're brushing your teeth, to the way the fork scrapes along your teeth as you eat. I'm not saying these small things are the reason for people breaking up, I'm saying it all adds up.
Anyway, I'm not secretive with my body or its functions, or anything of the sort. I just know what is rude or unappealing and like to avoid doing so around people I respect. It all falls down to respect.
It's like when I clip my nails for instance. I always either go outside, or to the garage, or bathroom. Why would I want any loose flying clippings to land on the carpet, couch, bed, etc. It can easily be avoided, so why not do it. To me, someone farting, burping or picking their nose all day long has an equal sex appeal as having terrible breath.
I don't scream to have the door closed when my girlfriend walks in on me taking a number two. But yes, I'd be locking the door just so I can have my 5 minutes alone and uninterrupted.
Edit: And I'm not saying you should be uncomfortable all day long because you've got a cork in your ass trying not to fart. I know how painful that can get when you're with a bunch of attractive woman and badly need to let one go. It's better to let them go then it is to hold them in. But there are moments when holding it for the extra few minutes is the gentlemanly thing to do. Or just roll down the window in the car - no one likes dutch ovens.
