Ishmael would probably be. She hasn't really felt the feeling of having her body worshipped since when she was with queequeg, so it's really embarrassing for her. She'd be blushing to high hell, questioning how on earth you enjoy this, while you fill your tongue with the taste of sea salt.

Rodya though wouldn't be embarrassed at all. Hanging out beside her too long has a 70% chance of her deciding to grab your face and bury you in the forest of armpit hair she has as a joke.
