Only monogamous relationship for me, yeah.
I did try other options, friends with benefits and stuff, but nothing actually compares to me, not even close, with the partner who intimately knows me, cares about me on all levels, and knows of all the things that turn me on.
Besides, sex in relationships is a continuation of a deeper feeling, a way to express love and a special kind of gentleness. Yeah, I'd say sex is very romantic to me.
But nothing bad with other options if you're into it! Monogamous folks are often portrayed as boring puritans who tell people what to do, so I'll stress that - you do you, but my drive works this way. And boy can monogamous sex get kinky...
It's often good! giggle
