Advise?

Mostly happily married for 22 years, since I was 21. We married as young and brainwashed christians. Its been 9 years since we left but here I am mid 40s and I’m soo unsatisfied sexually. She’s a once a week type the sex is just ok. She’s not open to anything happening outside our marriage and I’m struggling with wanting to cheat. We have two kids—12 and 10. I love her and def will not leave her and a part of me thinks the guilt would eat me but another part of me thinks I may have to embark on a double life if I’m gonna stay married ironically.

And yes, I’ve talked to her already about things and etc., she knows I struggle with other women and honestly as a fairly attractive guy it’s gotten really hard.

Thoughts or advice? Should I take the plunge?Does the guilt go away or lessen? For any of you who haven’t confessed or been caught do you feel like a psycho or do you feel it’s necessary and you get used to it?
