Is it natural that most of the guys I find really attractive (sexually and physically) bear some resemblance to my older brother?

That's creepy. Pero kung idol mo naman si older brother then pwede.

Genetic sexual attraction - Wikipedia I don't actually think this applies to you, but there is a tendency for siblings who first meet when adults to be attracted to one another. But I digress

it a physical resemblance you find attractive or are there other aspects?

i guess i you are in good terms with your sibs, it happens. like, well my younger sister and my older brother are totally best friends when we were kids. my sis' bf now, resemble my brother like the bf is a long lost brother. of course, there's a lot of differences. but the similarities are uncanny.

same with my bro's previous gf. she resembles my younger sister from a far. but she looks very different from her. the stance, height, built is similar to her tho.

That's the irony. We had a falling out and I'm not in touch with him for quite a long time now. I don't really like his personality kasi tamad s'ya. But somehow I find his semblance quite pleasing. Tho not attractive sexually

I'm more close to my older sister than him. We were close before when we're kids but got distant to one another as we grew older

incoming bullshit psychobabble
So what I'm getting from this is that you're subconsciously looking for the man your brother could have been, the ideal older brother in your mind that doesn't exist in your family but could be a reality in a prospective romantic partner :v

Perhaps something like that. Isn't that how the dynamics of attraction work? We subconsciously seek something lacking in us in someone else?

I zoned out during Freud and Jung lessons.
They're outdated anyway

Is this something similar to Oedipus complex?
