That's not getting turned on by DDo, getting turned on by DDo would be more like...
Cosplaying as your character to get into the mood... or.... I just ran epic dragon and I can't go one more minute without having sex with you because this epic dragon was so hot.
I can already tell there are people who have never seen the WoW porn out there, I had one friend where him and his girlfriend had costumes and his GF was a Dranei in world of warcraft so she would paint herself blue and wear anal beads that had a tail on the end and they would get all hot and bothered role play style.
To me this is messed up and makes me think they're sexually traumatized or something.
Nep away.
It's amazing how people think their opinions matter to me. You have your opinion, I have mine, and I don't care about yours. (Especially when it's extreemily misconstrued.)

Causes and symptoms
Causes
The cause of the association between an object and sexual arousal may be adolescent curiosity or a random association between the object and feelings of sexual pleasure. A random association may be innocent or unappreciated for its sexual content when it initially occurs. For example, a male may enjoy the texture or tactile sensation of female undergarments or stockings. At first, the pleasurable sensation occurs randomly, and then, in time and with experience, the behavior of using female undergarments or stockings as part of sexual activity is reinforced, and the association between the garments and the sexual arousal is made. A person with a fetish may not be able to pinpoint exactly when his or her fetish began.
A fetish may be related to activities associated with sexual abuse.
Welcome to being educated, when fetishism is listed as a mental disorder it tends to be classified as "****ed up" in slang terms.
I wasn't even calling your gf ****ed up because as you figured out from her statement she gets turned on by your excitement, your happiness or excitement is her sexual pleasure which is normal for a lot of females.
