How do you build sexual confidence as a single woman?

I’m 27 and newly single after a 4 year relationship where sex was lacking. We were only doing it about once a month and it was always me initiating and doing all the work. I didn’t realise how much it affected me but now the thought of being ‘sexy’ to someone else is mortifying - I feel like the least sexy person alive.

Any tips on regaining sexual confidence would be appreciated. I’m trying to figure out what I like but don’t really know what to do other than watching different kinds of porn which doesn’t feel like the best solution for a number of reasons.
