She [22F] is eager to have it, but I [22F] am not as interested. What should I do?

I've been in a relationship with my girlfriend for 8 months now. While I want to be intimate with her, I find that my libido is pretty low, and I don’t feel the need for sex every time we’re together. She, on the other hand, wants to have sex frequently, which creates a bit of tension between us. I think she’s incredibly attractive and I’m definitely drawn to her, but my desire for sex just isn't as strong these days. At the start of our relationship, there was a lot of passion—we were intimate almost everywhere, and I don’t regret any of it. However, lately, I find myself wanting different kinds of affection, like cuddling, kissing, going on dates, or simply spending time together without the pressure of sex. The crux of the issue is that sex makes her feel loved, while I find fulfillment in feeling desired even without constant physical intimacy. We both have experienced childhood trauma, which has shaped how we approach relationships and intimacy, but we’ve processed those experiences quite differently. She’s also the only person I know she’s ever felt attracted to, which adds to my guilt about how I’m feeling. I shared my feelings with her about not wanting to have sex all the time, but it didn't go over well. She felt rejected, which is understandable, and now she seems to be distancing herself. I’m struggling to find a way to help her understand my perspective without making her feel unwanted or rejected. What can I do to communicate this better?
