eddro,
Engorgement Has happened to me before as well and I have posted about my experiences previously.
I can’t give any diffinite advice but eventually I was able to wrap without the engorgement coming. Someone posted before saying it could be a mental thing because your brain may be thinking about the bigger dick you are trying to achieve.
When it happend to me and it was for a period of about 3 weeks I would put the hanger away and try latter.
I really do think it must off been a state of mind I was in even though I was not thinking about sex. I was probably just to mentally excited about having a bib hanger and a purpose for using it.
Like I said I have not had the problem since. I have not been as frequent with the hanger as I would of liked to be but I think for me it was all mental and when I restart hanging again I know that by resting when engorgment is around and not stressing was the way that I dealt with it.
Hope this helps you in some way.
