Any yaoi with good anatomy I can copy?

Ive been getting into anatomy for my art and have used mostly rl references but there's alot of details/muscles I don't really need for a stylized look and most stylized references ive found are not colored /not what I'm going for so I got a great idea to use yaoi s*x scenes (because I can see all the anatomy +colored and in all sort of postions) and yaoi in general, I have alot of yaoi in mind but the more references the better so do you guys have any yaoi with good anatomy or good art in general, also yaoi with everyday clothes like a college yaoi would be good to (also getting into dra wing clothes) mabye some yaoi with good lighting to
