Hi Roba,

Sorry your question got overlooked for awhile here.

Feeling nauseous could come from something physical or something psychological. Two things come to mind. One, I once read an article about women finding it easier being aroused with a full bladder (helpful for some women who find arousal difficult). Could your bladder be full and you just hadn't noticed? Second, I have heard of something called POIS or post orgasmic illness syndrome in which both men and women suffer symptoms after orgasm, such as exhaustion, insomnia, flu-like symptoms, brain fog, anxiety, depression, weakness, indigestion and so forth. Doctors haven’t come up with any solutions, but do suggest that dopamine and prolactin are possibly implicated.
