ummm how do I put this lightly…NOOOOO. absolutely not. This should absolutely not stop you from being excited over your chosson. He must be very special for this to be what you are concerned over.
Who told you this. And as for why you hear this at vorts-a few possibilities:
1) it just happens to be that way in some cases. that doesn’t mean it’s a requirement.
2)People are way too into “segulos” which have no mekor in halacha.
I really cannot reiterate this enough so I will answer your question once again. NO. really just no.
