It felt like previously I always had a very strong sex drive, needing to masturbate usually twice a day to get some piece of mind.
As I realized I'm not a man, for whatever reasons, my sex drive went down somewhat but was still strong. Masturbating about once a day.
I tried to define myself as bigender at first as a sort of "realistic compromise", but there came a period where I fought internally with myself about this and eventually understood I'm a trans woman and I need to do whatever can be done to get me a feminine face, so I decided to start with HRT, laser hair removal and working on my wigs. It took 3 months to get HRT authorized, during which my sex drive went down to masturbating once every 3-7 days.
Then when I started the actual HRT, it hit rock bottom. Masturbating once every month or two, and even then it felt forced just to see that I could do it.
9 months into HRT, I switched to gel and my hormone levels went back to male or near male. At this time I had a girlfriend for half a year already, my libido came back, I could finally enjoy sex not only from seeing her satisfied, but also feeling satisfied myself.
After 12 months HRT, I had an appointment where we changed the dosage and my libido is dead again.
Sometimes I get a spark of sexual excitement, but then I remember how much work it will be for me to maintain that spark, and I just feel it isn't worth it. Much better for me to just enjoy pleasuring her until there comes a day when maintaining a level of arousal won't be a titanic struggle for me.
