Hello Gio,
The little bumps you see are not related to HPV or warts, but appear to be the normal vulvar variation known as squamous papillomatosis (SP) which is also known as "vestibular papillomatosis". They may elongate and appear to grow, but this is due to the effects of estrogen, the physiologic hormone that guides vulvar, vaginal, and cervical growth and maturation in women of reproductive years. Nothing to worry about.
