Can vaginal fluids make you sick?

Sure if you drink too much of them.

Or inject them into your blood, more details will be needed to give any sort of solid answer.

Like what? I guess it depends on what you are talking about... need more details? I'm assuming you are a guy? Possibly talking about going down on a woman? Details lol... then maybe I can tell you a bit :)

If they smell anything like one woman I knew... the odor alone is enough to make you blow chunks... (yeah... that one left scars for life) heck, almost 25 years later the odor is STILL burned into my nostrils.. Fortunately that's NOT the norm.
