I highly doubt it.
Did she smell did that you make you nauseous?
Did the idea make you nauseous?
Did having your head down make you nauseous?

Everything was fine. No smell or discharge. It was just the strangest thing. A couple of hours after we finished I became violently ill with an upset stomach.

I can't figure out what else it could of been. Maybe it was just a virus that came about at an inopportune time.

Something you ate maybe? No pun intended (well, not really).

Try again to test it out. I don't know of anything that could have caused that - unless she uses spermicide...

The first time I ate out a girl I almost puked. Ur not alone I did it again . . . Not as bad. Dont think too much about it it might just be in your head
