This is something I've been pondering while working on a new book and I'd love some opinions. As long as a character is 18, are you okay with reading about him in sexual situations? Or is that still too young? What's your threshold? 18? 19? 20? Older?
And does it change when the story is historical rather than contemporary? Is having a 17-year-old hero okay in a historical depending on the mores of the time period? Does the age of the other half of the pair come into play? Say, two 19-year-olds is okay, but a 19-year-old with a 30-year-old makes you uncomfortable?
Does the plot matter? Would a BDSM story with an 18-year-old be off-putting while a sweet, traditional romance be fine?
Or does age not matter at all as long as it's a compelling, well-written romance?
