Hi guys i need help 1) So right now i want to read a manga( yaoi of course lol) a long one...

I really can't help you with versatile couples because I don't read them. I just can't get aroused, but here is a link where the couples are versatile in the relationship: http://www.mangaupdates.com/series.html?category=reversible+couple

Enjoy :)

1) Seito Kaichou ni Chuukoku
Hana no Mizo Shiru
Seven Days
Warui series (by Sakuraga Mei)
Crimson Spell
Underground Hotel

2) http://www.mangago.me/read-manga/kyuuso_ha_cheese_no_yume_omiru/
http://www.mangago.me/read-manga/sojou_no_koi_wa_nido_haneru/ (the sequel, surely the sequel will give your heart a ride to roller coaster of feels lol)

Thank you so much

Okay... not the best person to answer your request because I hate unecessarily lenghthy manga... but... I'll try my hardes i-i
1) Longer yaoi with non-girly uke :3

http://www.mangago.me/read-manga/sorenari_ni_shinken_nandesu/
http://www.mangago.me/read-manga/memory_of_the_future/ and sequel http://www.mangago.me/read-manga/kaze_no_yukue/ (Don't be mistaken by uke's feminine look xD He's stupid)
http://www.mangago.me/read-manga/kusatta/ (The uke-ish creature at the beginning turns out to be seme. Wait until he grows, man, wait. for. it.)
http://www.mangago.me/read-manga/himegoto_asobi/ (It's a spin-off, but stands alone)
http://www.mangago.me/read-manga/fake/ (Non-girly charries at all)
http://www.mangago.me/read-manga/takaga_koidaro/ and spin-off http://www.mangago.me/read-manga/aiso_tsukashi/ (Spin-off is better though)
http://www.mangago.me/read-manga/10_dance/ (Need. New. Chapters i-i)
http://www.mangago.me/read-manga/zetsuai/ (Uke is shoujo-ish, but he's got a wild look. Sequel Bronze has 14 volumes)
2) Reversibles manga

I know how you feel when there isn't a lot of what you want. I'm assuming you read the link I left for the person who asked the question, but let me help you even more. There is an American author/writer of a webcomic that she publishes online for free. The webcomic is called "Starfighter." At the beginning of the story, it is assumed they maintain a top-bottom sexual relationship, but as the story progressed they switch positions. Here is the link: http://starfightercomic.com/index.php
I don't know if you like reading novels, but there is a list of gay versatile romance novels at goodreads.com. Here is a link: http://www.goodreads.com/list/show/17384.M_M_Romance_Books_Featuring_Versatile_Couples
Hope I helped :)
