Meaning

Hi friends,

What does "turn her on" mean? It means "excite sexually" or "excite pleasuraly"?

“Did you get my note?” Jasmine would say to him as they lay stuck together. “What note?” would not be a good thing for Max to say. “Omigod, one of them found it!” Jasmine would exclaim. Then she would laugh. It might even turn her on, the consciousness of a third pair of eyes having seen the imprint of her avid mouth.”

Thanks
