New to sex

So I’ve recently started having sex . I know that a guy can throw off a woman’s pH balance but is there anyway it can help it too? I feel like having sex has actually helped my vaginal area. I usually take probiotics and drink GSE to help keep everything balanced and right down there , but lately I’ve been feeling like I haven’t been needing it after I’ve had sex . I’ve tried to google my questions but I don’t see anything that directly answers it , does anyone else have any feedback?
