Update - 02/04/24 - This LoRA still recieves a good amount of downloads. I would recommend not using this LoRA unless you NEED a 1.5 LoRA.
The model https://civarchive.com/models/288584/autismmix-sdxl can do all of these poses natively, which 1.5 models could not. I would recommend using this model for your Otoko No Ko needs.
You can also refer to https://civarchive.com/models/281404/lora-training-guide-anime-sdxl for my settings on training LoRAs for this model.
NOTE - This is a huge LORA with an experimental optimizer, main issues seem to be tagging is slightly rigid, and there is some loss of detail and color when generating. Reducing LORA weight from 1 to 0.9-0.95 does help with this, so play around with it. I'm mostly interested to see if other people experience similar issues with blur/colors.
USE TAGS 'Masterpiece, Best Quality' - Fixes the consistency issues with generating and generally increases quality.
Tagging - Each concept has a trigger word, but in general I have not seen this make a huge amount of difference. I would suggest testing concepts with and without these words. 'NSFW' tag seems to be hit or miss and is inconsistent with results:
General tags - Otoko no ko, male focus, 1boy, penis, testicles
All Fours - OTOAF, all fours
Condom - OTOCON, condom on penis, condom (works best without penis/testicle tags but YMMV)
Cowgirl - OTOCOW, cowgirl position, cowgirl, boy on top, sex, anal, yaoi, multiple boys, multiple penises, pov
Doggystyle (kind of works, RNG) - OTODOG, doggystyle, sex from behind, 2boys, yaoi, anal, sex from behind
From Behind - OTOFB, from behind, ass focus, ass
From Below - OTOFBEL, from below
From Side - OTOFSI, from side
Kneeling - OTOKNEE, kneeling
Legs Up - OTOLEU, legs up, ass
Missionary - OTOMISS, missionary, anal, yaoi, sex, 2boys, multiple boys, multiple penises
On Back - OTOOB, on back, spread legs
On Side - OTOOS, on side, ass
On Stomach - OTOONST, on stomach, from behind, ass
Penis in Panties - OTOPIP, penis in panties, bulge (seems to be the strongest tag, recommend always using this)
Penis Under Clothing - Bulge, erection under clothing (this is heavy RNG but I've seen it work)
Sitting - Sitting
Squatting - OTOSQUAT, squatting, from behind, spread legs, facing viewer
Reverse Suspended Congress ( - HEAVY RNG, does not seem to work consistently on some models as it's difficult to generate the male behind the target. YMMV but it will probably work well coupled with another LORA for this position.) - OTOSUS, 2boys, yaoi, sex from behind, reverse suspended congress, anal, faceless male
Good luck.
