I have tiny bumps on my vaginal lips. No foul odor and no itchyness.what's wrong? Is this normal?

Yep. It's probably sweat glands... are there many of them, tiny? Very normal. Google genital warts and see for yourself the difference. I used to get freaked out about this, and made my doctor test me three times for HPV.

I haven't looked in maybe 25 years but I've had those my whole adult life, and I'm 65.
Any part of you that is enclosed and against other body parts can get permanent and temporary bumps.
Eyelids, earlobes, folds around mouth, armpits, under breasts, but mostly groin from stem to stern. Men get just as many on their penises as women do on their vaginas.
