I had a similar experience. My sex drive crashed within the first week of HRT, but steadily recovered to almost where it was pre-HRT. And I retained function, which I could have done without, right up to SRS at 13 months on HRT. On the upside I'm functional and still have a high sex drive 9 months post-op and after 22 months of HRT. My T has been lower than where yours is from about 8 months into HRT.
In the end I'm happy that my body is so adaptive and everything works without T. Lots of folks have low or non-existent sex drives post-transition.
Just tuck tightly and avoid naughty thoughts. 😉
