My HSTS girlfriend keeps having less and less sex drive with me. If I initiate and keep going I can get her going, but she always finishes super quickly and she never initiates anymore. She's hinted to me that she gets a little annoyed at how often I'm horny, that I don't have to make her aware of it, she suggested that maybe we practice abstinence from ejaculating because she thinks it has "health benefits".

She tells me she has low sex drive because she's taking oral estradiol and spironolactone.

Is she bullshitting? Do the 'mones actually do this?

I can't tell, we have been in a relationship for like 9 months but she was on psychostimulant meds which made her insane for the first 3-4. She only took like a week break from HRT in that time and started it around when we met after a prolonged hiatus from HRT in which her T returned to normal male levels. But also she's pretty batshit, kinda cluster B, regularly cries about how her life is going and needs constant attention and emotional support, and she said she left her last boyfriend because she projected the feeling her life was stagnant onto him and also "got bored with him". Do you think she is actually losing sex drive because of the hormones or because I spilled too much spaghetti, failed some shit test, she's getting bored of me etc and will probably leave soon?
