Maybe one more...
The three milks, Angel, Devil, and Your, are some things that I've relied on quite heavily in my playthroughs. You can get Angel and Devil Milk for free over time from the Milk Farm after doing its event and finding cowgirls and appliances to make it better. The former reduces arousal, the later increases.
Your Milk is obtained from the Milk Pump when you milk into a bottle and heals a substantial chunk of health (100-ish iirc)at the cost of maxing out arousal, making it a great quick heal when in most places outside of battle when paired with Angel Milk. Make sure you have Bottles and remember that milking until your are dry will stop lactation.
I'll leave the utility of this info up to you. I slept on these items until after the current climax of Fawn's route.
