I am a female teen and i shave my vagina pretty regularly. i usually shave it twice a week. It has gradually been becoming more painful post-shaving. I am guaranteed razor bumps that are red and cover the top. They itch very bad and don't really seem to go away easily. I am asking you what i can do to prevent those bumps/rash to appear after i shave. I have read about calamine lotion (which i have). Would that be a good solution? Maybe vaseline? Please respond asap and thank you for your time.
