I agree w/ lilith begging for any type of contact is different. i think it shows that a couple doesn't respect each's other's desires or lack there of.

My husband and I do the other type of begging and pleading though. My husband is a huge tease and loves to bring me to the point of cumming and the he stops, watches, and smiles....and then I start begging...and i've done the same as well. I've found that all that build up leads to very intense orgasms for both of us.
