How do I make husband find me insatiable

This is more a problem and I need some advice please. Just found out hubby has been sexting and talking to ex on phone. We have been together 17 years and thought we were okay. Sex life good and I do know he loves me but this sexting her has me worried and angry 😤. Btw she did suggest having an affair with him about 10 years ago - she’s one of these women who likes what she can’t have. It didn’t happen. Can you give me suggestions on how to make myself more desirable to him I want to be the one that he finds insatiable and desirable. I do have a lot of love honey lingerie that turns him on so no problem there. Tell me how to really turn him on.
