Bruno Mars- Gorilla
The woman licks Mars guitar in this part of the video- which is a very sexual gesture, seductive and erotic. Her hint of a smile to Mars and invitational eyes, full of mischief, looking up at him comply with the 'invitational' facial expression identified by Marjorie Ferguson. The way that she grabs the guitar off of him is quite sexually aggressive, she is taking control of his possession which might be seen as quite sexy and provocative.
In this clip the woman is soaking wet, which people might associate with things of a sexual nature and men may find it sexy.
