See a lot of different types too!
There's an elderly couple living in my mom's block... both
white-haired already but still holding hands, walking slowly around
the neighbourhood! Awwwwww... 
There's also this elderly couple in my block, they don't hold
hands, but they're always going here and there together, talking,
discussing things, sounds quite business-like but it's their brand
of intimacy and routine, and suddenly, one day, I see the uncle
sitting on a bench, staring at nothing, looking soooooo desolate!
I
thought, 'Oh dear God, please don't let his wife be dead or
something like that!' Next few days, saw the uncle again twice...
kept feeling worried and kept wanting to go up to him and check if
he's alright. Third time I saw him, I buay tahan, this whole thing
haunting me already, so I walked up to him, gave him a huge smile,
'Good morning, uncle!' then we started talking. I slowly brought up
the subject of his wife... wah... like treading on glass cause not
sure of the answer and his reaction... he said, 'oh, she's a
Filipino-Chinese, she went back for her holidays, will be back a
month later. I miss her!' PHEW!!! Not dead, not sick!! PHEW!!! I
was getting soooo worried that uncle will get into depression!
Now,
his wife's back and I don't see him sitting alone at the bench for
hours anymore.
Ah well, each of us have different levels of intimacy needs, I
guess. We just need to find a partner who's likes the same stuff or
is willing to meet us on middle ground, ie. compromise. 
Like what elindra said, men are mostly clueless. I've learnt that
when I tolerate until super buay tahan, I'll just say, 'Can you
like hug me or not? A hug would be nice now!'. Usually, the blur guy will, 'Oh!' then big grin and
a huge hug.
Then, both will be happy!
