Kinks cannot be hardwired because many of modern kinks did not exist just some time ago LOL

But otherwise normal people get bored by everything. No matter how much you like it after some time you will get bored and either you will need to increase intensity or move to something else. You are not supposed to go away from it you just notice that you do not like it anymore. In fact, it even works with drugs as eventually you just notice that taking them is a totally useless waste of time. At that time some try to increase the dosage until they croak and some just drop it and move to something else.
If you fail to develop other interests by that time you will be screwed.

this is not so much about some kind of fetish but specific personality type.
some people are attracted to people and some people are attracted to things or actions or other stuff, and people are just tools.

I can see it even here as different kind of users who are obsessed with certain characters and do not really care wahst those characters are doing and another type of people who are into what those characters are doing but do not give a shit what character it is.

If your girlfriend does not arouse you, you are the later type. Women don't like that. They want to be objects of your desire themselves. They dislike when they need to make some extra effort to arouse you. In fact, this is even considered disorder in psychology as "fetishism"
So do not blame your preferences blame your lazy girlfriend who is probably not willing to do anything more than get naked.



Either way, for everyone with such problem my recommendation is to stop trying to get off.
Do something more creative do even something what you are not really interested

If your girfriend wants to fuck, you still have a lot more appendages on your body than your dick and they can work just as good or better. Also, there are numerous household items that can be used. Male penis is also known to be the worst device for making woman orgasm so not a big deal if it is not getting very hard.
