Help!

Okay so my girl always seems to smell, everyday. Just smell like sweat and like I haven't showered, but I take a shower DAILY and I even use vagisil order blocker I just noticed it's been starting to smell a lot more the last couple weeks.. Anyone know what could be the problem?? I know I don't have an STD/STI cause I am very anal bout that and get checked every 6 months! My girl is very well taken care of Lol. I'm just not sure if it's only me or what
