Is it normal that i masturbated to virtual sex?

Like if you've ever played Sims or even Grand Theft Auto... Like when you pick up a hooker in GTA and they get up on your dick and just ride you like a steer, the sounds and the image just flatters me and I just can't stop my urges.

Sorta like the same thing with the Sims, when you go to woohoo or even kissing on it. Just makes me so hard.
