@Impossible_PhD @goatsarah well i personally meant it as a positive value in the basis that many transfeminine people who consider adding progesterone do so for its anecdotal benefits to sex drive so the fact that it seems to fill that role is a positive result.
for those who'd rather not have a sex drive then, dont they can continue to not take progesterone? or try it out and if there is an uncomfortable increase then that person can stop taking it.
as long as everyone has more options to achieve what they want from their lives and bodies thats the importantant positive.
