Has anyone else noticed this ?
Up until about 3 weeks ago I had very sensitive nipples which could give me me multiple inner orgasm and also began to develop sensitive breasts that were also extremely pleasurable but now all the sensitivity and bliss linked to them has totally disappeared and I wondered if the pumping was the cause ?

This might indicate nerve damage? Stop the vacuum pumping for a while. If you haven't killed off the nerves, they will recover but it takes a while. Have you been overdoing the pressure or session duration? If so, you might be causing damage that might become irreversible.
Be careful, people have fucked up their boobs with too much or too harsh pumping.

Hi Heavens night, Thanks for the warning and info, i am pretty mellow on the pump , not too long and never over the top pressure, I will take a break and see how it goes, it is quite addictive though but i would rather have that blissful sensation back than bigger "dead" boobs !

Interesting I have been pumping for a few years and my nipples have become more sensitive and larger. Hoping you recover your nipple sensitivity

There's been some bad examples on how vacuum pumping can go wrong. I experienced some issue but none of it ended up being serious. My good friend Mel87 got a nasty complication from pumping in which she almost lost her boobs due to connective tissues breaking and almost going into necrosis. But she has fully recovered now from what I understood.
Also there's been some persons who have got nerve damage which can happen if nerves are pinched for too long without time to recover. Frequent breaks, different cup positions and being gentle on pressure can quite easily help avoid all these issues.
I found vacuum pumping early on quite effective boost to my development, but I've grown much more than ever before after I quit. It was at the point where I was outgrowing even the largest cups I could find and the width was getting uncomfortable. So anyway, I know its effective and its also a lot of fun and addictive.

But its best done as a supportive stimulation rather than the sole method. Overdoing it might also end up causing ton of scar tissue build up if its done to the point of continuous blistering without healing in between. The point being that scar tissue inside breasts looks exactly like a tumor so it can masquerade as breast cancer.
So, moderation is the key to pumping.

For me I've noticed that increased nipple size has caused a noticeable reduction in sensitivity. I have gone a bit extreme and for some time used electric nipple pumps. So after pumping my nipples are a good 1.5cm long and quite thick. I enjoy having them like this - they are so nice to play with. They'll stand a bit of firm or rough treatment so different sensations can be generated. It seems logical that something as big as that wouldnt be as super-sensitive as its smaller counterpart - because the nerve endings are being spread more thinly over a larger surface area.
