Is it normal that i like she hulk stuff?

When i was a kid I see an episode of 'The incredible hulk" in that episode Bruce Banner did a blood transfusion to his cousin Jen walters and she starts to transform into a Hulk woman, she moans a lot and says sexy things, That was my first erection, Since then I watch porn videos of women repeating the same process, becoming sexually excited green women. A few years ago I have a girlfriend and I love that she says the same dialogues that she hulk on that episode, my girlfriend becomes more aggressive and more eager to have sex, she loves that, to break her clothes and to feel that she is a green free animal, is that something normal and if so, what is the name of my fetish?
