Anecdotal evidence suggests that sex drive, or "libido" response, to HRT is case sensitive. Libido happens in the Limbic System of the brain and is conditioned or predisposed by cultural conditioning, overall health and brain chemistry. A healthy lifestyle and psychological state before HRT should support no significant loss of libido with the reduction of T. Of greater concern are alcohol and tobacco, substances shown by research to lower libido. A person in good general health should be able to tolerate lower T, but this is something for your physician to help you manage. There may be some trial and error to find the right balance for you and your partner.
Before HRT, I had zero libido. I hadn't had sex with anyone for 15 years, became indifferent to it altogether and only masturbated infrequently for health reasons at the direction of my doctor. Thankfully, after starting HRT, my libido returned. I began HRT with E only for the first three months. A T-blocker was added, and this did not lower my libido, which is quite healthy. My T levels are consistently in the low-normal range for females.
There were changes, though. Orgasm became less intense as a sudden, brief sensation and became a deeper, longer duration sensation. I can have multiple orgasms whereas before I could not. Also, there is little-to-no semen ejaculate as a result of HRT, but to me that's a good thing. If the lowering of T reduces libido, it's not irreversible if it becomes a problem. I know the site is open to younger readers, but as a nurse, I haven't used any language that isn't included in a middle-school sex education class. I hope this long answer helps.
