I have been a single parent since 31, and went a really really long time without sex. Sometimes it bothered me, sometimes it didn't. It took until my son turned 16 to be able to prioritise this aspect of my life. But that is what I had to do! I am 10 years older than you, and sexual opportunities weren't just going to land on my lap!
First thing I did was start taking care of my self again. Losing weight, better clothes etc. I was positioning myself as a sexual being again.
I started to notice men more out and about. Relearned what attracts me.
I hit the dating apps and met lots of men for coffees until I found someone I was attracted to and the opportunity presented itself.
I also did lots of research into sex and my body to give myself some confidence again.
This was about a year's worth of effort! It was also important to me not just to sleep with anyone. I had to want that person to stimulate that desire again when it's not been part of your life for so long. Perimenopause hormones helped!!
It is very very hard to carve out a sex life when you parent children full time alone. Carve out some time for solo sex. Treat yourself as a person to be loved. Sow those seeds and your time WILL come again.
The positive side of prolonged celibacy is that it is a bit of a reset, an opportunity to know yourself and develops your standards so that when you do find someone to have sex with you will be in a strong position to advocate for your needs.
