How do i know if i am predisposed to being sensitive to androgens? on loestrn fe 1/20 for a year and do not have acne or body hair, am i not sensitive

No acne: Not having acne is a good thing. Not having it likely means you are fortunate. Unless you have a complete absence of hair including pubic hair then there does not seem to be a cause for concern. Genetic make up, ethnicity and body weight are some of the contributing factor in the distribution of body hair. If you have no pubic or armpit hair at all then evaluation may be needed
