Update: Added PonyXL version.

Trigger word is different to illus version, "pee in uterus" is the most important trigger word for PonyXL version. (adjust the strength of "pee in uterus" if you feel this LoRA weak)
Additionally, "cross-section, multiple view", and "x-ray".
Weight might be fine around 0.5~1.

更新：PonyXL版を追加

PonyXL版は、Illus版とは違い、"pee in uterus"が最重要トリガーとなります。
他には、"cross-section, multiple view"と"x-ray"ぐらいですね。
比重は0.5から1ぐらいで良さげです。

Trained on noob v1.0. Might work best for noob based models, but also works for pure illustrious xl based models.

Illustrious can kinda...handle this situation by default with some prompting technique, but without LoRA, word "peeing" triggers female peeing severely, and also very unstable. This LoRA significantly decreases female peeing while peeing inside situation, and stabilizes it.

trigger word: "male peeing" ("peeing inside" or "internal peeing" may also work)
Additional words: "pee in pussy", "pee in uterus"(for cross-section), "cross-section", "x-ray"

I'm not sure about quality, and also not sure about which weight might be the best, but it seems to work at wide range(0.3~1.0), so try yourself.

Also, this is not an intended behaviour, but it also seems to work for "pee in mouth" thing.

Noob v1.0ベースで、Noob系のモデルで一番よく動きますが、普通のIllus系でも一応動作確認はしています。

IllusはLoRA無しでも一応、本当に一応は、プロンプトによっては膣内放尿もできなくはないですが、"peeing"が女性の放尿に滅茶苦茶強く結びつけられていたり、動作が安定しなかったりしますので、このLoRAはそれらを改善し安定化するために作りました。

トリガー："male peeing" ("peeing inside" や "internal peeing" などもいけるっぽいです)
オプション："pee in pussy", "pee in uterus"(断面図補助用), "cross-section", "x-ray"

クオリティーはちょっと疑問が残りますし、どれぐらいの比重でいいかもちょっとよく分かりませんが、結構適当でも動くっぽいので(0.3~1.0)、試してみて下さい。

また、意図したことではありませんが、"pee in mouth"（口内放尿）とかも割といけるっぽいです。
