Seems nice but... not much in common... sexual attraction not very strong... kinda sweet but pushy about Tantra. What's the question? I don't understand the struggle.
Just because we're poly and we have an opportunity to date other people doesn't mean that just anyone gets the privilege of being with us. Sure, poly enables one to appreciate people for who they are and not pressure others to be who they aren't, but we're not obligated to try and fit incompatible people into our lives, like square pegs into round holes, just because there's an "opening" available.
