My pubic hair barely extends to my inner thighs. it only extends to the outside top part of my pubic hair. i still have barely any pubic hair on my inner thighs, only a very small amount on the top of it, does that mean im in early tanner stage 4?

The amount of hair has no bearing on your health. 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. Wish you good health! Safe sex: https://www.hopkinsmedicine.org/health/wellness-and-prevention/safer-sex-guidelines

Not all people reach Tanner V (5) in appearance, but they are fully functional sexually mature adults. With hair extending to the inner thighs, you have reached Tanner V and you need not worry at all.
