Well... I think I won't find many characters similar to Yashiro in yaoi. He's so unique 🙂

Then I started wondering how about female version. Maybe some josei or seinen has similar characters?

if there is, i want to read.

but maybe this one might seem interesting;
Koibito Play

If you can describe him, I could probably think up a few.

Well, Yoshiro was raped by his stepfather when he was child. Then he immersed himself in sex with a lot of men, he claims to be a masochist. In highschool he somehow fell in love with his friend but nothing happened. They remained friends (Yoshiro still has some feelings for him but he's already taken) Later Yoshiro become yakuza boss... Then a new character came, his new impotent bodyguard fell in love with him but there are some issues... The series still ongoing.

So: Yoshiro is very sexual, but more important: he is twisted, painfully lonely, blunt and shameless. He never shows his real feelings. He's bitter, ironic, sarcastic, hedonistic, witty, inteligent.

General everybody look down on him, except his bodyguard who adores him, and maybe some men interested in his body.

Well... his behaviour is harmful for him... in kinda similar way to main hero of movie La Pianiste by Michael Haneke (woman who had a strange relationship with her mother, is addicted to porn, and it affected her relationship with her lover)

That sort of rampaging personality can be singled out in oneshots but in series, I could think of two girls.

Flag time - Murakami is the protagonist's love interest. She is beautiful, popular, clever, etc. Although she's playful and daring, she doesn't appear emotionally invested in anything or anyone. She doesn't act too bothered when her boyfriend cheats on her or when her teacher molests her. She forces the protagonist, Moritani, into risky sexual situations. You'll get the feeling Murakami is just manipulating Moritani, but in recent chapters she has been developing feelings for her. Ongoing.

Citrus (Saburouta) - Mei is emotionally distant. She has daddy issues. A prim and proper rich girl who tries to bury her emotions and insecurity by being physical/sexual with others. Which makes her a conflicted character, one that abides by all the rules and is never amused by her older sister's antics, but she's desperate to have value to someone and will play with her sister's desire for her. Ongoing.
