Not for any ideology, anyways. I don't think that sex is - or even should be - that big of a deal. I can't marry until at least 2 years - preferably 3 - into a relationship, and I would prefer to actually know the person.
My first priority in these matters concerns stability. To marry during a so called "crush" would be foolish, and it would be more prudent to understand one's partner on a sexual level as well as on any other level, than to simply ignore it, mainly in order to develop so called "companionship".
The prospects of a "first month-divorce" attract me not.
P.S: And as for ceremonies; I am asocial; I am cheap; and I am non-religious. Do the math. D.S.
