Taboo sex dreams?

I feel horrible... I keep having really amazing sex dreams about an ex... Its usually about when we have actually had sex sometimes its new and Omg does it "feel" spectacular! But I feel horrible because I'm married and I feel like I shouldn't be having these dreams.

Sex with my ex was just so passionate and exciting and with my husband I just feel like its a wham bam thank you ma'am kind if thing... There's no touching, controlling etcetera as when I was with this ex. I love my husband and have no feelings towards my ex other then the sex was out of this world... Please tell me that I'm not the only one who has dreams about their ex's????
