Real penis >>>>>>>>> Plastic penis.
Even if the plastic one vibrates, moans, plays music, even has any vague forum of ejaculating some fluid, or whatever. Real penises >>>>>>>>>> Plastic penises.
Even having you on the phone it would be consider masturbation since she is... uh. alone. And we ALL know that masturbation is good, but real hot steamy sex is better :D
She won't replace you for her vibrator. She won't replace a human being with a piece of plastic. The human being not just does the job, but cares, loves and supports her. I think, that 9" plastic tube won't love, care or support her.
Chill out man. Enjoy having her on the phone. Enjoy masturbating while on the phone. Just make sure you have enough to pay the bill ;)
