I would say fluid build up is what is being reported above.
I was surprised at how heavier my unit became after sessions where I got fluid Build up.
It doesn’t last longer than 12-15 hours though, unless you go hard in the pump again .
Yes totally agree with this, the edema is probably the cause if this was almost over night results.
However the dual attack to get girth in my exp works very well. I do clamping and pumping and it really works. as long as just be low the skin is not puffy then it is legit. I remember when I was in the first 6 months of pumping I through I was great with new girth…. most of it was just edema/lymph
Also the pain can be cause because the skin is puffy and does not enter and exit the vagina in a normal way, which can be uncomfortable. Cation needs to be taken when getting girth as it can lead to troubles in sex. Right now I mostly cannot have sex with my girl without lube, I esp can’t have it touching the clit the entire time.
There is a trade off is my point.
Good work continue the research :D
