This happened to me in the past and I just spoke with another Noogler who had the same problem after starting breast enlargement supplements (PM or pharma E). We are both genetic males and I don't know if it could happen to genetic females, but it's worth reporting this.
After taking supplements for a few months, thus raising the level of oestrogen in the body, the skin generally softened and got thinner. One side effect of this is that using the same amount of vacuum with Noogleberry caused the appearance of blisters and even the rupture of some thin blood vessels around the areola (which can take months to disappear). If you are already a noogler and intend to add supplements, remember to use less vacuum in the cups and, instead, favour lower vacuum for longer periods. With oestrogen the skin becomes more elastic but it takes longer for that than for the thinning, so there is a period when it's weaker.
