                                                ^ basically sums it all. 
i won't be going on a personal definition but rather my observation throughout the years of reading BL. shounen-ai can also feature sex but they usually cut half of the body or do the "fade to black" cut. normally plot-centric than sex.
meanwhile, yaoi is smut-oriented. it equates to "ecchi" in het mangas. plot varies from paper-thin to rich. but generally has lesser plot compare to shounen-ai.                                            
 
																				I love your way to explain! lol
