Okay ladies I know this sounds absolutely CRAZY (and really nasty) but every time I swallow my SO's semen I get exploding and horrible diarrhea! He isn't the first and only person I have had oral sex with so the first time it happened I thought maybe it was something I had eaten. I woke up at 3am so stinkin' sick (thank goodness he didn't wake up)  it it only lasted for 30 minutes or so. So some time had passed and I yet again swallowed, and yet again I woke up in the middle of the night with it basically running down my legs. At that point I started thinking and wondering if it was his semen causing it. I have looked it up but there really isn't any research or anything on it. Has this ever happened to any of you?? If so, did you eventually get used to it?? Or what??
