"I think we're all, as humans, obsessed with the forbidden. We struggle to find a strong sense of identity and we all have unmet needs and deep wounds. It's easy, especially in today's society, to try to meet those needs in the wrong places." -- Brandon Cox, pastor
"Let's set aside mental issues and pathologies and deal with 'normal' people reasons. My top two reasons are, first, you aren't getting the things you want out of a sexual relationship and you go elsewhere. Or, secondly, you get bored with your present partner. If people aren't getting the quality of sex or frequency [they desire], they'll supplement on the side, but will still love their partners and want to stay with them." -- Eric Amaranth, sex life coach
Being attracted to other people is normal, but...
"It's natural for humans to be attracted to others -- whether a physical or emotional attraction, or both -- but in a monogamous relationship, individuals must recognize they feel an attraction, but overcome any desires, as adultery is a sin." -- Rabbi Jason Miller, rabbi
