From what you described, you are not a risk of any infection from smelling her panty. Even if your face contacted her butt cheek the risk of any infection is less than miniscule. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV and Covid vaccines.
