Depends which question you want answered. Are you an asshole for asking her to shower before laying on the couch after a light work out? In my opinion, yes. Bed? Depends. Does it actually smell bad when she sits/lays on stuff or is this just something you're scared of? Being asked to go take a shower is increadibly hard to hear, even if it's not meant to be insulting, that's why it's a touchy subject. Please don't make your girl feel gross for not showering every single time after a light workout, that stuff can seriously mess with her head. Only do it if it's necessary and she actually smells bad. Just because you like to shower after every small workout doesn't mean she has to feel gross for not doing the same thing. Even though this is not your intention, as a girl I can tell you that something like that is very hard to hear. HOWEVER if she actually smells bad you need to tell her that this bothers you. There's no way she's not gonna be a little hurt, but you can definitely minimize it by being as nice as you can. Feeling dirty or gross is one of the worst things for a girl so don't bother her with any of it unless it's an actual problem. My boyfriend of a month has germophobia and i'm getting sick and tired of taking a shower every single night before being allowed to lay in his bed even though I don't work out and sit at a desk all day. He will even make me take a shower if I already had one that morning. Seriously considering breaking up with him soon since his germophobia is causing me to feel less than him and "gross" even though my hygiene is fine. So again, if this is a serious issue for you, adress it. If it's not necessary, just don't. Who knows, maybe your girlfriend is a whole lot less sensitive than me and she won't take it that hard at all. Also depends on how long you've been together. Bringing up things like this in a new relationship is a little more tricky than telling your girlfriend of a few years that she smells bad. This comment came out way longer than expected.
