It's a vasodilator, so blood would rush to any available spongy tissues.

It's a common misconception that Viagra makes you horny. If gives you an erection, but as most guys know, that doesn't mean you are sexually aroused.

The brain, for the most part. Which is why Viagra is useful for migraine headaches.

Yeah its effects are only physical, giving a man an erection, but men can get erections even when there not horny at all, waking up with an erection mainly is due to the mans bladder, needing to pee really bad, it puts pressure on the prostate which gives a man an erection, but he might be 0% horny, so they are two different things.

So im pretty sure it wouldnt do much, i think maybe because the clit and labia are spongy that they might get aroused but thats a guess, and again it wouldnt make her horny id imagine.

It will probably make you dizzy. Might give you a headache.

Probably nothing special if girls would take just one. Maybe some sude effects like headache or dizzynes.... Maybe more blood in brain, internal organs, maybe evn in clit and labias but taht means nothing.
AND its dangerous to take medication that is not prescribed for you.

Lol nice question.

Probably not much :3

Off-label though so you can't get a refutable doctor to prescribe them for that. Which sucks.

lets not find out... we dont want anyone in the hospital now do we? :p
