Actually I think that most of the swelling from vacuum pumping is interstitial fluid and not technically 'lymph fluid'. Also, since the swelling goes down rather quickly, I doubt it has much if any deleterious effects.

The main problem with bras is how long they are worn and how constricting they are over a long period of time, especially if not sized correctly. I would guess that the intermittent nature of noogling does not cause the same kinds of problems since it isn't sustained for long, uninterrupted periods of time.
