I want to have sex out of marriage 😰

I have been happily married to my husband for about a decade and love him a lot. We have sex and enjoy it too.

But i am weirdly having dreams of having sex with other guys/women when i like their looks/ as a person. I am disgusted by the thought and wondering why i keep getting this dream.

I watch lesbian porn, never tried it. When i see a busty good looking women, i dream of kissing her and her boobs.

I never met a colleague but we talk for work. Now i am meeting him next month for work and we are staying in a hotel. I keep dreaming about having sex with him

Do anyone else have these? Why do i get these thoughts?
