I am writing a story and the boy just turned 18, in the story the 24 year old man is the 18 year old boy's teacher and they have amazing sex. The teacher falls for the 17 year old boy but they do not have sex when he is 17. He is blinded by lust and he becomes a little insane and the 18 year old boy is accused of only staying with the 24 year old man because the sex is good
It is legal but ethically dubious - Teacher would be fired if it came out - Maybe have relationship outside a school teacher/pupil environment - Age gap a little pronounced but not major, I would be comfortable enough with it then.
that doesn't happen, guys are not into other guys as "that" common, unless your writing gay porn stories. and i wouldn't be into a story like that, unless the teacher was a girl, then it would be practical.
BoysLove is not my genre but i already read a book that contained a detailed sexual scene between 2 males and also some innuondo in other scenes. I had no problem with it because it was 1 scene in a good book with more than 1000 pages and it was important for the story.
