Not on reta, but I have the same issue on tirzepatide.
I've always had hormonal problems though and an increased libido thanks to PCOS but it had mostly calmed down to "normal."
It's very difficult for me to tell what is due to tirzepatide, the weight loss (I went nuts for awhile when I lost 70lbs and ended a whole 7 year relationship the last time), heading toward mid-30s, being off birth control (except I never got the libido killer side effect from it like a lot of women do), but it is frustrating and I feel you 100%.
It's even worse because my boyfriend is 10 years older than me, struggling with low T, high blood pressure, and being overweight and would rather listen to his friend who is a supplement bro vs. actually treating ANYTHING so our sex life is stupid so I'm trying to come to terms with this relationship heading towards the end too, which is a whole vent you did not ask for!
edit cause I mixed people up ignore me lol
