my downstairs area

kay so ive recently been having sex with my boyfriend and we’re super chill about it and comfortable with everything and anything, but now i’m getting self conscious because i’ve noticed that since having sex and using lube, down there had started to get a certain smell. He keeps trying to go down on me but I’ve been putting it off for days now cause idk if it’s just me smelling something or if it actually does.... keep in mind there’s no itching or burning... what do i do to get rid of the oder ?!
