Optimal Penis Length for Comfortable Milking Table Use?

Hello, This milking table looks AMAZING!! Is there a specific penis length that would be needed to be most comfortable for the person doing the milking where they wouldn’t bang their hand on anything close to the opening?


This question is about Folding Milking Table

Glad to hear you find my table amazing! There’s no minimum dick length to use this table , it has a rather large opening of 12" long and 8" wide. The beams underneath are spaced out as well to not get in the way.
