hum masturbate??

i'm not a minor btw, so i never masturbate before and i'm a girl, and recently my dad bought me a message vibrator stuff like that, so i used it but i feel weird since i's my first time xD, so my questions are...


1. how long is it to cum normally?
2. i never cum so what is it feel like when u want to cum? (i'm afraid it's a pee)
3. the best spot in pu$$y?
4. how to keep the vibrator clean?

thank you, please answer it seriously (人 •ᴗ•)
