hello yaoi lovers my friend recently said that she will give yaoi a chance and wanted some...

maybe this one?
http://www.mangago.zone/read-manga/seven_days/
it's actually shounen ai but for a starter I think its really cute:)

or if it has to be a yaoi than maybe this one !

seven days is best choice for beginner.
or other shounen ai :

I second Seven Days!!
Also some others:
http://www.mangago.zone/read-manga/full_moon_ni_sasayaite/ (a little bit of gender bender so she can ease into it)
http://www.mangago.zone/read-manga/ani_no_hanashi/
http://www.mangago.zone/read-manga/silver_diamond/ (not focusing on love, but bromance is still apparent)
http://www.mangago.zone/read-manga/new_york_new_york/ (what got me into yaoi, a little mature in story, amazing, and I'm pretty sure there aren't any explicit sex scenes)
http://www.mangago.zone/read-manga/shinkuu_yuusetsu/

http://www.mangago.zone/read-manga/gimmick/

Oh I chose all shounen-ai btw, the most is a make out probably or an implied sex scene but not really shown.

Hope it's not too obvious a suggestion. Honto Yajuu was one of my first yaois and is still a favorite: http://www.mangago.zone/read-manga/honto_yajuu/

I think sex scene is not a problem, many people like yaoi because of it. HA+ (>‿O)v For example me, I love yaoi because of 'Crimson Spell'..
The problem is dark twisted, violent theme..

I recommend Rutta to Kodama. Or perhaps Golden Eyes or Bukiya Na Silent.

Hana to kurumi to amai seikatsu. I think this is yaoi, but I'm not really sure.Well at least till chapter 6 its pretty fluffy. ヾ(❀╹◡╹)ﾉ~
But I guess Seven Days is perfect; its sweet and fluffy.Beginners may get a little miffed to see gay sex immediately so I think its better if she or he starts slow :) Or If you think they would be okay with yaoi you can recommend them Slow Starter or that sequel of Doushitemo Furetakunai, whose name I can't recall. But it was very fluffy :) Or maybe Kanjou Spectrum! That was the second shounen ai manga I had read after Seven Days, and here I am :)
Definitely don't make them read Harada's works at this stage. They'll need to take it slow.
Hope that helped~ (=・ω・=)
