Ladies please help !!😭

I have been getting this so much lately.. and I’m itchy down there and I think it’s because my partner sweats and doesn’t shower and then has sex with me or bc he cumed in me the other day orrr bc he doesn’t shower as much... might be a yeast infection ? I’m a super clean person but this is just bothering me . There’s a lot not just that ^ throughout the day it’s always moist and all the discharge comes out looking like that ^^
