On the one hand, no. It is not lame. On the other hand, as Mr. Ubuntu before me said, if you build it up too much, there is no way the reality will live up to the expectation.
There is nothing wrong with having an ideal to live up to, but life is not a magical Disney movie, a Hallmark card, or a Lifetime network movie; you do not have to save your first intimate everything for who you consider Mr. Right, because you will find that the pressue you put on any Mr. Right will become to try to live up to the Mr. Perfect in your head, and that is an unrealistic expectation to place on both yourself and everyone you will ever date.
That lightning-strike, butterflies-in-the-stomach, love-at-first-sight, ga-ga-eyed, schoolgirl-first-love is a very tall order. Love is not an instant electric connection, love is effort, love is learning not just your lover's heart and body, but learning their mind as well; love is trust acquired through trial amd time, love is coming to understand one another and learning that you can place your faith in each other, because you have spent time together through thick and thin and understand each other as well as you understand yourselves.
All of what makes a lasting love is the exact opposite of what Hollywood and Disney say real love is; according to fairytales, love is instant and permanent, it leaves you helpless and stupid. Real love takes time and effort, it makes you strong and sharpens you. Two lovers working together is a beautiful sight, but again, that kind of romantic dynamic takes time and effort to discover and build, but it is well worth the time and effort spent when it is successful.
Your ideal is certainly romantic, but you must temper your fantasies so that real life has a chance to catch up. I wish you only the best in your search, but never be afraid to question your beliefs and put your ideals under a microscope.
Never let anyone or anything stand in the way of your happiness, not even yourself. Most importantly of all, never forget that you matter, and you are not alone.
