Hygiene

Okay soo Before i start this im not trying to be mean or judgemental but my husbands hygiene hasnt been the best lately , I sometimes have to nag well not nag but remind him sorta to brush his teeth or lets shower/bath . Im by far not perfect but i do try to maintain a good hygiene like shower or bath twice daily if not once & brush my teeth , Iunderstand he works sometimes 2-10 or 3-11 but To come home , literally strip down into underwear and not shower ... this isnt the first time hes done this ... Its becoming a problem not just for me but for him as well, I dont want my husband to smell bad or be talked about because ive been there i know what its like , idk if hes use to doing this in the past but i saw old photos of him and his baby momma , he was dresssing A1!!!! & now with me its like hes barely trying . I dont know how to address it in such a way that wont hurt him , Please Help i need advice
