Well I'm really turned on and I feel my vagina pulsing , is this normal ?
Yes its very normal to feel that
yes, i think so, blood rushes to your vagina when you are turned on.
When you get that feeling as sally says blood rushes to your vagina if you was to look at your vagina and spread your lips you will probably notice your clitoris has become slightly larger and more erect and probably changed colour a little and the colour change goes for your whole vagina.
Some times it is actually possible to see the inner vagina pulsing. :-)
