Do people agree that the unexpected, the unconventional, the taboo often gives added spice in sex? I remember when I was 18 I met a former teacher at a football club party; she asked me for a slow dance, kissed me brilliantly then gave me a hand job out the back. I got off with another girl later that night but it's the teacher I remember now because of the forbidden nature of what she did...
It's luck of the draw, nothing else.
It's only remembered as forbidden fruit when it goes well, when it goes wrong it's simply a mistake.
It ain't anything special, it's just a choice as any other is.
I bet Eve found it irresistible only when told she mustn't eat it! Otherwise just a watery Golden Delicious (see: an example of where the name is tastier than the fruit!)
