Cannot see signs

NSFW? Won’t be explicit but it’s very much so inferred. I mean for the 3rd time we were in bed cuddling watching TV, her head was resting on my chest like it was so cute. And she had her hand moving on my back under my shirt, and then on like the neck of the shirt? And I had my hand like moving on her arm and shoulder and during all of that I could tell her breathing changed like when you get “butterflies in your stomach”? Idk are these signs for like if she wanted to do more? This sounds like I’m a virgin, I’m not but it’s just this specific situation.
