I live with two bisexual women. They have as much sex as they like. I even get to watch and jump in for a threesome on occasion. I have never felt that I was left out or unloved. As long as you are strong as a couple, a little non-monogamy can't hurt you since she is seeking a sexual relationship. You are not interested in polyamory, and you don't want her to call them girlfriends etc. I suggest you two have an honest chat about your relationship and keep an open mind about her sexual needs. What if the positons were reversed?
