I got rid of the ick. Last year, I got the sort of ick that stopped me wanting sex. I'm 49 and think it's part of perimenopause.
I found the more I thought/worried about it, the bigger it grew in my head. I was overthinking it, googling herbal supplements, etc, and it took up more space in my thoughts every day.
Then, I stopped doing that, and thought instead about the few times I do still want sex. Because I do, sometimes. Nowhere near as often as I used to, but it's still there, half-asleep in the corner. I don't let it worry me any more: if we're both up for it, it happens, and I don't overthink the reasons it doesn't the rest of the time.
I had an honest talk to my partner and explained it's down to my almost-50 hormones, not him, and luckily he was understanding.
I'm probably never going to have the libido I used to, but I'm fine with a less energetic one. Honestly, my hottest bedroom fantasy is a quiet room to myself and a good book. :)
