Im f26 and work an active job. I shower once or twice a day. I use a loofah and lather my armpits with antibacterial soap for at least 30secs each, rinse, then lather with shower gel. After im dried off i still smell a bit musty under my arms. I don't think I smell bad, but I don't smell fresh either. It's like a faint whiff of old sweat or something. After I've put on deodorant I smell fine. I just want to feel/smell clean after I shower tho. I feel like I do something wrong. My parents never taught me how to properly clean myself and kicked me out at a young age. I learned I had to use a wash cloth from a boyfriend I had at age 16 lmao. I think I do good job now with my hygiene, but my armpits are bothering me.

English is not my first language don't come for me

EDIT: Holy shit. I went to work, to bed and woke up to so many more comments than expected. Thank you so much for helping me out. I'm off to work again but i will read them all the comments when I have time and try your suggestions until I find one that works. You guys are awesome, thank you!!
