I can see where an arranged marriage could be nice because you know that both the families already approve of each other. I think sometimes people forget that you are not just marrying a person, you are marrying into a family. When the kids come along, it is nice to have that strong parental support for good relationships with the grandparents, etc. Also, if her family is unstable that can be a drag on the marriage, even if she is a wonderful person.
Also agree with TigerLilly that I think waiting for the right person for sex is very romantic. I am always very suspicious of "players" who have so many partners.
