Hello,

A different smell after sex be it fingering, grinding oral or penetrative, some times it just happens. It depends upon your vaginal PH level. Vaginal PH is very important in keeping your vagina healthy, normally pH should be acidic and if it is alkaline, it can temporarily change your vaginal smell. If done orally, one can induce a smell as saliva contains bacteria also of the oral cavity.

If you are using a condom for protection as a barrier method, it can also induces smell. Going back to front during sex of any kind can definitely cause a change of smell. After anal sex, bacteria in and around the anus could cause bacterial vaginitis or UTI. It should go away after some time, if not, it should be investigated. Sweat, diet, even menstrual pad and your underwear can do it. Your vagina contains a number of bacteria.

Take care. Hope I have answered your question. Let me know if I can assist you further.

Regards,
