Nerdgasm in human sexuality?

Studying for my Human sexuality exam and getting too distracted by technology news (reading comments about 'nerdgasm'), I wonder why isn't there a term for nerdgasm; The affection humans give towards technological advancements.

Not to mention news of Japan marrying a manga character/ video game character or even inanimate objects... What does that categorize as?

Edit : Paraphilia (The general term used. I still can't find the specific term for such cases)

And, this question appeared in my final exam =.=

I wanted to answer paraphilia but I keep thinking there's another term for it. I looked around and found nothing... So I guess that's a -1 point for me...
