I experience a huge confluence of both groups of symptoms upon an orgasm. They are so intense, they happen simultaneously upon orgasm, yet i experience them to a lesser extent leading up to the crescendo of sexual activity. The symptoms become more and more intense as I approach orgasm, as well as some pleasurable feelings which are supposed to increase, but only do to a minimal extent. Most any pleasure I do derive from sexual experiences are is muddled because of all of the symptoms. I then need to be combine sex with more stimulus to get minimal pleasure despite hypersensitivities. Sex is a double edged sword we are all too familiar with.
In terms of actually symptoms:
I. Cognitive
1) Migraines
2) Confusion
3) Word finding issues and stuttering, stammering and spelling problems
4) Memory (short term in particular)
5) Orientation and balance
6) Physiological (deep depression and mood swings, )
7) Focus problems
Hypersensitivities to sound, light and cold
9) Phantom pains (sharp and dull ache)
10) Spots and floaters in eyes
11) Tinnitus
II. Flue-Like
1) Chills and hot sensations
2) Burning and tingling sensations deep in muscles
3) Burning and tingling on skin and brutal rashes (acute- on genitals as well as neck, forearms) (raised and red bleeds when bad) (dandruff/ hair loss/ itchy scalp)
4) Asthma and scratchy tight throat
5) Fluid retention and swelling of the face hands and joints (dark circles under eyes and pale face)
6) Deep muscle and joint aching
7) Exhaustion (Sleep for 12-14 hours the day of orgasm)
Tooth pain
9) Irritable Bowel and indigestion
If you experience a similar array of symptoms I'm very curious. I hope my information is helpful.
