I use this as well, works great

I think a heat shield is a very good start and better airflow would definetly improve things. Watercooling an ECU seems very exessive and overcomplicated however.

Great detailed comment, thanks. I kinda was looking for a genuine comment since it‘s always nice to read about othe peoples practices and knowledge. I do wash my genital area just with water as you described and it works great.

Ask yourself: do you watch porn to get off, or do you watch porn because you like the act of watching porn and not primarily the getting off. If it‘s the latter in my opinion it‘s time for change.
