and that these factors aren't mutually exclusive
Short bio:
I have been experiencing POIS for many years without ever knowing there was a term for it, how many other guys suffered and how different the symptoms could be. For me, problems probably started around mid to late puberty as I was doing a lot of PMO (porn, masturbation, orgasm). Aside from general symptoms of brain fog and tiredness which almost all guys in the Nofap (i.e. abstaining from PMO) communities report on without necessarily having POIS, my primary symptoms are and always have been varying levels of itching/urticaria and bad skin with acne and what I can only describe as dandruff with an oily scalp.
I'm 25 now, and as stupid as it sounds never seen a doctor for these issues. I also haven't cured myself, but found periods of complete relief through Nofap, only to fall back into what can sometimes feel like a literal fire depending on how much and how often I give in to the desire of sexual release and my vices. Since it dawned on me that POIS (still without knowing the term) was the culprit I have sort of managed my symptoms for years by not going overboard with PMO, and trying but most often failing to do Nofap. The most I've managed has been around 20 days to a month only a handful of times, but anytime I go longer than a week or two it's almost as though I never even had this shit to begin with. Skin clears up with no excess oil and the itchy urticaria which when active is also onset by physical stress and sun exposure gradually fades away
Now, things to note that led me to believe this is true:
- acne is most definitely primarily hormonal in nature. there's a reason why teens and women who are pregnant are most affected and not prepubescents or other adults to the same degree
- my own symptoms can be onset just by sexual arousal alone (orgasm is a stronger and longer lasting trigger but still)
sidenotes:
diet especially can improve and worsen acne, but it probably happens through changing our hormones. see
https://goo.gl/qrw96h the only medicine that made my itch tolerable at its worst was antihistamines, which means there is an autoimmune reaction but again, because of the first two points this is probably also directly due to hormones. see

https://www.ncbi.nlm.nih.gov/pubmed/19087438 for a possible explanation that ties in to the other references as to why a generally healthier diet seems to be the cure for some
Couldn't find much in the way of identical symptoms on the forum, but I hope that it can resonate with someone on everyone's journey to being free and finding a more clear cut cure
