frenzy (emotional …, esp. as caused by something unattainable) n.: nympholepsy
[This word often, though not always, refers to an erotic frenzy.]
The night before last [the young woman took] a shower in the main bathroom, and left the door open. I looked right in, right through the transparent shower door, and saw her, a full-bodied [woman] oiled with water. And saw myself as well, in the fogged mirror, amid the steam, a peeping old [man] in a silken gown in the throes of nympholepsy.(Alfred Acorn, “Chapter 9: Wednesday, Oct. 18,” Salon.com, 7/18/2001.)
