I lost my sex drive almost completely in the 90's when I was on HRT the first time around. It sort of returned after a years once I stopped, but I found I really did not miss it much. It returned eventually to a "healthy" level eventually and I enjoyed it ok over the next few decades.
Now that I am back on HRT, it takes a unanimous vote from congress to get anything going. I am fine with it, but it does seem to annoy my better half that she has to work so hard...spend so much effort. The one thing she has said though, when things do get going, they REALLY get going and that is 7 months with high dose E.
I actually like my toned down sex drive as 40 years of being ruled by it never really suited me. Okay, maybe "ruled" is a bit dramatic, but it was not something I considered a positive.
I have a couple of sisters that have completed SRS and they said taht they feel the same drive they did at about a year on HRT alone, but they enjoy what they have a lot better.
