Oh, gotcha. As Lissou mentioned, the connection between testosterone levels and libido may not be as clean as you would like—there are plenty of women with low testosterone and lots of libido, for instance. I guess you could even temporarily test it out yourself. Get some grey market anti-androgens and/or estradiol, which can lower your testosterone. Try them for a month or so. It's possible that they might make you feel better, but, well, if they do, it's probably not cuz of a libido drop.
