Sorry for the delay. Many posts were stuck in pending because of spam. I have checked your messages and will answer your questions here:
1. Ejaculations: The number is limited only by your stamina. You can enable 'Detailed stats' in the settings to see how your 'M stamina' restores.
2. Visuals: This is a 2D game with some obvious technical limits. Also we aim for realistic sex simulation. For example, a stomach does not swell from sperm in real life, so we do not show this in the game to keep it realistic.
3. Account: To create an account, just enter your email and password for the first time. Please use a real email so you can restore your password later. You can find more info about saves here >>
