Ways to show love to my girlfriend

I'm facing a somewhat unique challenge in my relationship. My girlfriend and I (in a wlw relationship) have been navigating our different ways of expressing love. While we both cherish physical touch—even simple gestures like holding hands—things get a bit tricky when we're out in public. I struggle with anxiety and come from a strict, homophobic upbringing, which leads me to shy away from any public displays of affection. On the other hand, she enjoys showing affection openly and often feels down about my discomfort, although she makes an effort to understand my perspective. I'm looking for advice on how to make her feel loved in a way that aligns with both of our needs or how I can manage my anxiety about being queer in public. I live in a fairly accepting city, but it's hard to shake the habits I developed growing up. Any suggestions would be deeply appreciated!
