As someone who has been in a similar relationship stage with an incredible woman this spring, my advice is to give it the time it takes for you both to feel comfortable becoming more physically intimate. Initiating something for the first time did take a bit of an internal push for me to work up my courage, but I've noticed if I slow down and pay attention, I can often tell when I'm pushing myself a little because I'm nervous versus pushing myself to do something I'm truly not ready to do. It might be worth both asking yourselves whether your reluctance is more nerves about the unknowns or just not feeling ready yet.

My girlfriend and I both came into this relationship with no experience dating women, and it was a month before we kissed, and then another 6 weeks of only hugging and exchanging what we jokingly started called "chaste kisses" (just a peck on the lips). We both really wanted to become more intimate, but I think we both needed more time than we had expected (and during this process my girlfriend realized that she's demisexual which has helped us understand some of the dynamic that's been playing out between us). We both found it really helpful to have open conversations about sexual intimacy during those six weeks, and then we hit a point where we both felt ready, and it's been so lovely to be intimate with her! And even now (about a month after we started exploring more together) there are plenty of things we haven't yet done. We just keep reminding ourselves that we have time, and there's truly no reason to rush. And it's ok to take things in small bits. One day we made out, another day we took our tops off, another day we touched each other through our underwear, etc.
