It is in yaoi, but shounen ai isn't
Yeah but they only show their hands.. Lol idk tbh
I it depends on the author. I've read Manga with those tags and it showed full body steamy sex
it's mostly in the middle area. also, there are times that the tags are just a mistake.
baka updates is more reliable if you doubt if a certain manga is yaoi or shounen ai.
If a BL is tagged with shounen ai and yaoi, is there any sex scenes?
