Littlewit's little wit

In the opening act of the play, Littlewit, Win, Quarlous, and Winwife are engaged in a conversation, during which, Littlewit blatantly allows the other gentlemen to kiss his wife.  Win is very much in protest against this action and finds it ridiculous that her husband allows, if not, encourages it.  After Quarlous's kiss, she exclaims, "Why, John? Do you see this, John? Look you! Help me, John (1.3. 37-38)."  Littlewit replies by telling his wife that she has no need for objection, saying, "They'll do you no harm, Win, they are both our worshipful good friends (1.3 45-46)."  It seems quite strange for a man to allow others to kiss his wife, especially while she protests.  As we learned from "A Woman Killed with Kindness," extra-marital affection was scoffed at (to say the least) in this time period.  Littlewit's attitude seems to be quite a contrast to that of Frankford in "Woman Killed."  Having said that, what are we to expect from a character with such a name as "Littlewit?"  Jonson seems to be offering a glimpse into this man's apparently dim psyche right off the bat in the play.  This first act seems to set Littlewit up for complete failure as a husband and as the learned man he is expected to be (I'm not sure what a "proctor" was at this time, but I'm assuming it is a profession similar to that of a lawyer).
