I imagine Ariel's sex life is full of curiosity and enthusiastic exploration. she's never had a vagina before, she wants to learn how it works, and she's used to having to make her own assumptions about things on her own. I can easily imagine her shamelessly sitting with a mirror to look at herself, touch these new parts, and then report what feels good to Eric in her girlish, open way. shed be excited about everything, and her desire for new-ness would keep them from falling into a pattern. Ariel, in a word, strikes me as adventurous.
