<human>: Provide a brief overview of the text.

To begin: we're solidly in love. Foundation of incredible trust. We knew we were best friends on the very first date. So delving into swinging isn't the most dangerous thing, given that we trust each other so much and our communication is open. 

I am sexually open, very progressive, but a lot of me just wants a relationship that follows a standard path. We're meeting a couple for dinner tonight and I feel sleazy and alienated from him, despite his empathy through this.

Is his instinct to explore sexually just not compatible with my sensibilities? I think he is the most sensible, logical, liberal, empathetic person outside of this. Makes for a hell of a dilemma.

I want to be with him for the long haul. Can one have a serious long-term relationship after swinging?
<bot>: Boyfriend is excited about swinger experiences, it makes me a little alienated. Can't shake yearning to have a completely "normal" relationship. Am I making a huge mistake to stay?
