Forgive me but you say the question is 'misleading' and then you talk about personal preferences. That not the question I asked, although I accept that my eloquence may not have been obviously clear.
Maybe I missed the specific relation of your question, in that case forgive my imprecise response.
What I was asking is can the desire for this be borne from something in our DNA? The reason is, I never experienced this and when I first saw it in a clip, it immediately felt a connection and didn't know why.
DNA plays a role, but predetermination through DNA is not in the slightest comparable to the influences gained through experience (which includes everything - every experience in life including upbringing, positive and negative experiences (which do not necessarily have to be related to ones erotic emotional interests) and emotional situations) on one's own development.
Moreover, development is never complete, it can theoretically not only expand but also change over the course of one's life. Could. In most cases, however, sexuality will no longer change fundamentally after a given stadium of development, but will either consolidate or expand.
Hope that explains why "individuality" is based on experiences over lifetime, not mainly DNA. DNA is more or less a factor in ones hormonal-emotional (not purely thought-emotional) development and decisions, but less so in the basic interest.
As example: if someone would be predetermined by genetic traits to have a high temper, have a higher adrenaline level, leading into direction of attacking, insulting, fighting or - the contrary - self-despising, self-blaming results through hormonal level differences or the build-up of the related brain regions, this can surely play a role in how later sexuality will work out in real life.
But it doesn't define the interest behind ones sexuality. It merely defines the "how does one act based on the sexuality". And even this is quite easily able to get overpowered by mental control, it's no trigger which enforces one to do specific actions (only if there's no interest in not following those => missing mental self-control).
In regards to your "when I first saw a clip..": Surely enough you can have interests, even if you never knew precisely where or what those are aimed at. That's not uncommon.
And if you see / feel / experience / recognize the right aspect, you might feel like you did.
But the interest behind.. is neither "made" through the clip, nor "rooted" through the clip. It could only set a thought-direction into something which either was predefined by your experiences (and maybe to a very slight amount in your genetic, but that's merely a sign for direction, no road which only -leads- in this direction, big difference).
Or it could combine your interests which are already given with a "goal", a target. Which might be what your interests are based on.. or might lead to something comparable, "almost" the interest, nobody knows how precise "your" interests were beforehand. It's all an individual development and not made from granite with hard-engraved directions.
