Are there any new freaky yaoi manga (not manhwa) out rn? Like, maybe a monster boyfriend, stalker, BDSM, paranormal, etc.
Yes we have a legit yaoi story about a monster boyfriend.

Any bl where the seme gets his ass eaten and maybe fingered?
this couple is kinda covered in 3 volume
first volume is in this compilation https://www.mangago.me/read-manga/bi_no_isu/ they are the first pair (ch 1-3.1)
second volume https://www.mangago.me/read-manga/kobi_no_kyoujin/ this is where the thing happen (in chp 4). honestly not rlly successful (? not a nice example lol) but tbh this kinda open my eyes at that time
if you like them, they have this bonus sequel https://www.mangago.me/read-manga/bi_no_kyoujin_smoke/ (if i'm not wrong) the thing was a ome time thing tho
Pls give me a bl rec to hurt me (with no death). Like the seme having sex with a woman in front of the uke to hurt him, or the uke using a kind hearted seme for his own personal gain, or a seme who only hits up the uke for a good time even though they were friends before.
Doesn't have to specifically be any of these, just something with a similar vibe.

Any bi 3p? Two guys, one woman. Where the guys are bi and into each other and her

Honorable mentions:
https://www.mangago.me/read-manga/what_happens_when_the_second_male_lead_goes_on_strike/ I read the novel and my headcanon is that they're a platonic throuple lmao
https://www.mangago.me/read-manga/camellia/ the novel ends with the cross-dressing bisexual FL having both a wife and a male lover, BUT the wife and male lover are not into each other and FL is not an actual man (she's so convincing I actually forgot at some point though). I still loved it so I'm including it :D
