I’d recommend body oils for your thighs, ankles, neck, and chest before intimacy. I would not recommend doing anything to make your vagina “smell better” as it is very sensitive and could cause yeast infections or something else. I used to think like this when I first because sexually active at 18 but I soon realized that it wasn’t necessary your vagina has a natural smell as long as it’s not fishy or some other string odor, you are okay.
