My girlfriend has vaginismus, and it's impacting my feelings for her.

I'm feeling unfulfilled in our relationship at this point. We've been together for a year, and while we started off quite physical, we’ve never engaged in penetrative sex due to her inability to do so, which I’ve accepted. However, I do need some level of intimacy. Initially, we were physically affectionate, but it seems to have diminished since she started birth control. We haven’t been intimate for several months now, and it's really affecting me. I’ve tried to talk to her about it in a compassionate way, expressing that intimacy is something I need in a relationship, but she tends to shut down and not respond. I genuinely believe that physical intimacy is essential for a relationship, and right now, I feel like I'm lacking that connection. I don’t feel loved or desired, as she rarely initiates any sort of sexual interaction. How can I effectively discuss this issue with her and work towards rekindling our intimacy?
