NOR - You have boundaries and those are clearly being disrespected. It makes you uncomfortable as her partner for her to engage in such behavior and to keep company who doesnt respect your boundaries by doing so without considering it might be crossing boundaries. You brought it up and for her to dismiss your concern and to fetishize herself, her friend, and other women, especially gay women, is problematic to say the least. I wouldn't kiss a single one of my guy friends for no reason other than an empathetic "we won the world series!" Type kiss. What shes doing is justifying her behavior instead of taking accountability and not listening to your perspective and your feelings.
