if the ones i'll give won't meet your expectation, sorry! these are all the only ones i currently remember
http://www.mangago.zone/read-manga/fuck_buddy/ it's still BL but i think in the first chapter they actually did it together with a girl? (haven't read it)
http://www.mangago.zone/read-manga/faded_first_love/ main guy's love interest was a girl, then shifted to the other guy. there's no smut tho
http://www.mangago.zone/read-manga/fucked_by_my_best_friend/ kind of??? because the MC turned back and forth from being a guy to a girl; love interest seem to like both sides
http://www.mangago.zone/read-manga/the_genderswapped_host/ similar to previous one
i've been looking for the first one for so long, thank you!
http://www.mangago.zone/read-manga/an_innocent_sin/?f5i0 (ML is bisexual, there is also the story with his ex)
http://www.mangago.zone/read-manga/thirsty_for_love/ (Who doesn’t likes sharing their girlfriend because she is a cheater? )
Gender roles on Tapas has a really and I mean really representation of bisexuality. It’s definitely worth it.
https://www.anime-planet.com/manga/bisexual (I also found this but it doesn’t seems to be on mangago)
ah yes, finding out your girlfriend is cheating on you, getting raped by your respected senior and your dead gf's exes, and then continuing to fuck them is very realistic 10/10
would try myself
Also i cant find the last one F but thanks
are there any stories with a bisexual main character? Not where we just hear that they're bi, but see it too. I've seen a couple with girl mc i think, but ive never seen it with boys. Well, only in BL have i seen it, but the mc never did anything with girls so its pretty useless info
