The "4 Ages of Man" Folio

[bi3mw]

Upon further investigation on the subject I want to check whether the so-called "digitus virilis" as a gesture could have a meaning here or not. All I've found so far are vague references. So I looked at the "usual suspects" and came across the Rutland Psalter. There is a scene with sexual content that could show this allegorical finger. Is this what is meant by "digitus virilis" ?

By the way, the position of the left man's arm is very....strange.
