I only JUST finally read this one https://www.mangago.me/read-manga/shangri_la_no_tori/ and I found it pretty similar to Saezuru (not about the yakuza though): similar dynamic/personalities, 'straight' seme who initially can't get it up for men x hypersexual uke due to sexual trauma, the way they both end up yearning for each other but can't be together due to their circumstances... but most of all IT'S SO GOOD I can't believe I skipped it until now
This or anything from scarlet beriko
