Going to drop a
little unorthodox here: You, indeed, show wisdom in your thoughts -
but this merely applies to your Higher Self. (In the simplest term
I can put: someone who doesn't succumb to the negative energy of
Mars/Lust. This is a very good thing by itself). Forum mates praise
you for this, not actually seeing the double edge:
...seeing couples holding hands is of like something
obscene for me...
because in my point of view "one thing might lead to
another". You 2 can be kissing , the next day frenching , the next
next day petting and finally the next next next day engaging in
full blown sex and what we get at the end of the day is a platonic
relationship in action.
This is not exactly
discipline... more like abstinence.
You want to prevent POSSIBILITIES, even if it doesn't neccessary
always have to follow the sequence like a book. IMHO, this is not
exactly healthy, for its ok if you are not comfortable with the
notion of sex before marriage. However, affections is like Love -
it shouldn't be held back. Holding hands is of like something
obscene to you? I am pretty sure, you may have to rediscover
yourself through your relationship as you grow older.
Simple affection does NOT equate to the possibility of sex. I think
such affections are wonderful things. If you want Love to go
somewhere, you cannot hold back on the gift of affections - holding
hands, hugging, kissing, etc are signs of NATURAL affections...
so natural in love is
like life is to breathing.
And there is too much logic in your mindset. Law and Order, fixed
concept and all the beauty of a civil mind. Prevention, issue,
problem, consequence, feedback and follow up... hidden in your
subconscious. You apply what you see happened to your close friend,
modified by your unconscious fear and go through alot of deep
thoughts - in the end, I can tell you that your result is mostly
blank. Which is why you ended up here, seeking for advice.
People would probably tell you 'hey, good guy.. continue this way.
You are a rare gem, probably the last man on Earth, etc' - but
ultimately DO you
get your fulfilling relationship? My answer is
probably not, until you rediscover yourself, learn to use the 'Art
of Emotional Science' and learn more about yourself instead of
overly relying on others for answers.
People don't see this: 'Because you are not subjected to lust
through great deal of mental, emotional and physical discipline -
such cosmic lesson is probably beneath your feet as you have
probably secure firm victory over it. People sees it as awesome,
because it's something they are trying to sort in their life. BUT,
NOT you. You have sexuality blockage... an
emotional discomfort dealing with affections. Holding hands is one
of the possibility leading to sex? If you are telling me petting
is.. I would have agreed. But holding hands?
Your girl said that you are not romantic - it's a bad choice of
word, thus you probably never knew what is the root of your
problem. The actual term is 'Not receptive/responsive to
her affection.' and therefore, unloving... and NOT
unromantic.
P.S: By telling how much you love her (or yourself), but lack the
proof in action, will tanish every single effort of yours in the
long run. I always say this "Love looks in the same direction." If
your definition of Love is this way, either you find someone who
shares the same definition as you, or you learn to love and
appreciate Love the way Love wants you to. 
Cheers
