The
concept of virginity doesn't even exist in the spiritual aspect of
love because it only bothers people who lead and perceive their
relationship in the lowest of all planes (CloUdiSm three realms of
relationship).
I find it simultaneously amusing and somewhat hypocritical for one
to proclaim love for another, yet having to be so bothered by this
virginity issue. It is logically impossible for relationship to
devalue, if your relationship is initiated by Love and not via
other elements. If the concept of virginity could diminish your
perception of 'Love' for your other half, seriously, it's not even
Love to begin with in the first place; therefore one would surely
be bothered with the analogy of being 'used' verse 'new'.
True Love is a constant that doesn't get affected by its
environment or any 'moment of truth'. This universal acceptance has
absolutely nothing to do with being magnanimous; rather, it's a
simple understanding in the mechanics of Love - of having
unconditional acceptance.
If you are even casting doubts on your relationship over such
mundane issue, I questioned the quality and definition of Love you
are seeking.
Here's some food for thought: does it necessarily mean that a
virgin girlfriend:
I) Makes a better gf?
II) Would enable you to have a more fulfilling relationship?
III) Would enable your relationship to last longer?
Without you answering: it's none of the above.
I see some illustrations with regard to why the concept of a virgin
girlfriend is 'better' - well, I would agree with them if you
perceive your Significant Other as nothing more just than
meat/possession/goods. Such unanimated objects are valued by the
usefulness of their existence; therefore, having it 'new' will
surely lengthen its usefulness.
Does it mean the same for your Love?
Do you demeaning the classification of personality, character and
soul of a woman to that of such unanimated objects?
Ironically speaking, how 'useful' is virginity?
Can it stop her from walking away (if she bends on leaving)?
Can it prevent your relationship from wilting?
Can it grant her to Love you again if she has lost that fiery
emotion towards you forever?
No.
Eventually, it only mollifies one aspect - the Self. The
exhilaration of unwrapping your Christmas gift and learn that your
toy is new probably gave your inner ego a satisfactory boost to
sneer around that your toy is brand new, while the other kids could
only be contented with 'second hand'.
Although you are no wrong in desiring a virgin mate when you are
likewise yourself, our expectation and our cosmic lessons hardly
blend in perfectly. In fact, it often clashes violently, giving
rise to conflicts of the mind and heart.
So what must you trust in face of these uncertainty?
Love, of course - Unless you never had it right from the
start.
You can't believe in something you don't have. 
Cheers
