## 🚀 Quick start

Trigger word: prvpns

Sweet spot: 0.55 for couples / penetration · 0.85–1.0 for solo close-ups

Base model: Krea2 pornmasterKrea2 or equivalent flowmatch stack)

Photorealistic male genital anatomy for Krea2 — veins, glans texture, scrotum placement, and correct attachment to the male body. v3 focuses on heterosexual penetration: better vulva junction, depth, and fewer floating / double-penis / futa artifacts than v2.

Gallery images are 100% AI-generated (fictional partner where shown — not a real person).

## 🏷️ Tags

Trigger: prvpns — keep it in every positive prompt.

Core: single erect prvpns penis · attached to his pelvis · heterosexual sex · exactly one penis

Penetration: penetrating her vagina · labia stretched around the shaft · penetration junction in focus

Do not prompt: silicone toy · dildo · blowjob (minimal / absent in training — confuses junction scenes)

Negative (copy-paste):

```

second penis, two penises, extra penis, futanari, futa, woman with penis,

floating penis, disembodied penis, penis on stomach, penis on torso,

blowjob, oral sex, silicone toy, dildo, fleshlight,

plastic skin, airbrushed, cgi, 3d render

```

Also fill Civitai version metadata: trigger prvpns + the core tags above (blocks separated by outfit/scene if you add variants later).

## ⚖️ Strength

| Scene | LoRA weight | Why |

|-------|-------------|-----|

| Solo close-up | 0.85 – 1.0 | Matches the main training concept |

| Couple / penetration | 0.45 – 0.60 | Best v3 balance — higher → extra penis / futa |

| Macro junction only | 0.50 – 0.55 | Tight genital crop, no face |

## ⚠️ Known limitations

- Strength > 0.6 in couple scenes often causes double penis / futa — stay near 0.55

- Won't fix a weak base checkpoint alone — pair with realism / skin LoRAs

- Macro shots work best face-free (genitals + inner thighs only)

- Occasional floating penis if the prompt doesn't tie genitals to the man's hips / pelvis

- Not trained for oral / toy-proxy penetration captions — use real vulva wording at inference

Rank 16 / alpha 16 · 2000 steps · [ai-toolkit](https://github.com/ostris/ai-toolkit) sd_trainer · base krea2_base_bf16 · 768×1024 buckets · bf16 flowmatch.

The 13 penetration shots are real vulva junction reference (side / rear / POV-below) — not a toy-proxy set. That is what makes v3 strong in hetero scenes.
