Alpha 4
still working on the missing color sliders and cum related bugs, thanks for your patience
Features
Doggystyle: Still rough with no collisions, breaks at some angles, can't lay down properly, needs a ton of polish and more details to be how I intend it to be, but at least it's finally here!! It's quite a leap, from fixed positions to a new freeform system that allows complete freedom of movement. This will lead to more freeform actions being added in the future, like kissing or prone bone. Hope you like it! I promise it will get better with updates!
Female characters can now have orgasms
Improved cum textures
Added the option to hide the male character and show only penis
Bow-leggedness slider
Fixes
Fixed vagina lips opening too much during penetration
Android versions respect user desired orientation instead of always rotating
Changing the height no longer turns the character into Quagmire
Removed some FOV limitations, in preparation for a future VR update
Alpha 3
Features:
Mood & Personality system:
This GIF may take a while to load
Replacing the old "emotions" system
The goal is to allow roleplaying different scenarios.
The current sliders are:
Extroversion: Shyness or extroversion, affecting how other moods play out.
Happyness: How happy or sad they are.
Dominance: How dominant or submissive they are. Dominant characters will initiate contact in future updates.
Crazyness: How mentally unstable they are. Unstable characters are unpredictable.
Tiredness: How tired they are.
Engagement: How engaged they are in the sexual activity.
Intoxication level: How drunk / drugged they are. At high levels they may pass out.
Anger: How angry they are.
Disgust: How delighted or disgusted the character is with their partner and the current situation. At high levels, they may refuse contact.
New ragdoll physics
This system is still in a
very early stage
, and I'm especially interested in your ideas.
What mental states would you like to see? What unusual actions or reactions could happen at certain mood levels? I'd love to make this system much deeper than a collection of sliders that choose what animations to play.
Nighclub toilet environment:
Two variants:
small and large
.
The grime and atmosphere can be customized, and it also introduces a new physics object that emits light (testing new logic for future scenarios involving physics-based cylinder-shaped objects)
236 New Voice Lines
Moans, groans, breathing.
3D audio, headphones recommended.
Sound at this scale is completely new territory for us, so
your criticism is extremely welcome
. Tell us what sounds good, what doesn't, and what you'd like to hear improved!
Want your favorite VA to voice PhySex characters? Send me a DM with their contact info and I'll look into hiring them for future updates!
Dynamic Lighting:
New dynamic lighting system.
Anal Sex
It's finally here.
Includes a bit of anus customization
Expanded breast customization:
Some developer tools are now exposed for deeper customization
It's a bit hard to get into but if you tinker with it you can get the freedom to make them look like you want without the glitches present in the previous "user friendly" sliders
Physics were also improved, breasts can now swing around in preparation for the doggystyle update
Lots of fixes
Expanded AI controlled sex:
Oral targeting options, to make the character automatically stimulate the penile shaft, testicles, glans or choose randomly between them.
Penetration hole selection: To switch between anal or vaginal sex, or to let the AI choose randomly.
Improved UI
Now sliders are searchable
Buttons instead of expandable panels for better navigation in mobile versions
Sex Position Saving
Your favorite positions can now be saved.
Expanded customization:
Expanded vulva customization
Nails customization
Removed limitations for arm sizes
New outline options:
Color
Level of detail outlined
Teeth customization
Alpha 2
Restored cum visuals including semen sticking to skin, like in the old prototype version
Added height sliders, but the female one is still buggy
Added new AI options:
Cum inside or outside
Manual, automatic or always available cum
Added 9 new front hair styles
Added 2 pieces of clothing
The AI can now detect when the glans is placed in their lips and will attempt to stimulate it
Removed glitchy breast shadows
Added more penile sizes
The character creation menu turns transparent when it covers most of the screen while editing the character
Restored the old default character look
Eyeshadow improvements + glitter
Jaw, cheeks and cheekbones improved to support more facial structures
Added the nightclub environment, but it's still very early in production. (Edit the mirror settings if it doesn't work)
Outlines now show up in edit mode
Added more translated text
Temporarily removed features:
Emotions have been temporarily removed while I refactor the character's facial geometry and expand how the system works like how the AI responds to different stimuli. At the same time, I'm improving the facial bone structure to support more animations, including custom ones in future updates. I'll bring emotions back in the next update!
Undressing interactions too, I'm improving the clothing system to allow "downblouse" at certain angles and positions.
Doggystyle, the AI emotions system and adding voices are my main priority and are being worked on behind the scenes, expect to see them soon!
Thank you again for your support!

Players like

Summarised from 11 written player reviews.
this is a really good start for something that could be cool, im a sucker for games that allow you to pose, customize, and then essentially do whatever you want and the "phys" aspect of this game really brings that…
this simulator is really good, if there was a gameplay loop with a little story and maybe other metrics where the girls reactions etc change depending on how much attraction you've built, all im saying is theres lots of potential…
I like it, hope the update comes soon. The physics are ok, the facial expressions are the best ones I've seen. The dev seems passionate about this project, so I'm hopeful for its future. I don't know what else to…
