You know.. it's so hard to find a yaoi manga that is well developed, long and not with a lot of sex scenes. there are MANY yaoi mangas that are well developed and long, it's just that basically, every single chapter contains a sex scene, but don't get me wrong I do enjoy me some good smutty scenes, but like no need for every single chapter （￣へ￣）
try shounen ai maybe?
I feel you :), that is why I like shounen-Ai better, but if you still like Yaoi's, then I can recommend
