In "Perfect Zen" by E. A. St. Amant it is written:
“You're a breeder voyeur,” Paulo remarked. “She loves the explicit gay porno stuff, like at the Barn.”
I found that a breeder voyeur is 'A heterosexual person who attends a gay bar or event in order to observe gay life', so, I'm wondering what do you call a heterosexual who, not only observes gay life, but wonders what it would be like to live and to have a relationship with a gay person.
The first word that come to my mind is curious, but it seems too general and I'm looking for a word that fits more precisely that meaning.
