My gf wants to stop estrogen

Hi! My gf (20,mtf) wants to stop hormones because her sex drive is now non-existent (as she explains it)

She doesn't want to quit because she's been looking forward to taking hormones. She can't find a solution, but she's growing frustrated with not being able to use sex as a form to release, as well as the pressure of not being able to have sex with me, or the pressure of people not seeing her as a woman if she does quit. (I already told her I didn't care what she decided! And I still loved her regardless)

Are there any tips or advice you can share? I want to help and support her, but sadly, I can't do anything with my limited knowledge of what she's going through.
