Those here are yaois with characters which do both (in threesome or just switching)
http://www.mangago.me/people/tag/1115/Switch/
and in those, they actually switch.
I still don't have that many tagged, but I guess it's a start.

Ah, I forgot, in this one they switch sometimes http://www.mangago.me/read-manga/haru_wo_daite_ita/

i got a collection of manga in that theme. go and look over http://www.mangago.me/home/mangalist/33677/ i did some little reviews on the titles as well. there's a lot in that list where pairs switch like it's all normal.

Almost all of Sadahiro Mika's work are Seke; e.g.

Just look at the right top of manga page, I believe you'll find some Seke lists or tag.

Including List/Tag of Suzume & takame. (▰˘◡˘▰)

thank u guys so much!! & i'm sorry for the late reply!!
i'll have a nice & busy week of reading seke if that's wat u call it lol
again thank u so much for our Help!!

excuse me i just have a question on one of the mangas on your list
it's about the manga "love me harder", u mentioned that yuma is a seme on the extras but wat r the extras that he's a top on?
please tell me because he is really hot & i wouLd liKe 2 see more of him
thank u!!

yeah i do agree that yuma is hot and can totally see him topping someone. as for the action, it was unfortunately only mentioned in passing at chapter 6. he was sex friends with his friend (the smaller one) and if you are okay with threesome, you can see yuma guiding and prepping his friend at chapter two.

oh ok, thank u so much for taking the time 2 reply 2 me.
i will have a woNderful time with your list you'e sent me!!
thanK u so much
