LOL at the option for "I please myself 5+ a week" and only a "2+ times with my partner a week" as a maximum option. You fail at understanding the potentials for marriage. For the most part our sex lives are better than that of a college sophomore, and this I think reflects your own bias based on your own experience of sex.
You miss the importance of emotional attachments. Plenty of people on this site are devasated by the emotional affairs their spouses have had.
Your entire research is worthless if you are fishing from a "having problems about marriage" website. This is clearly a non standard sample population.
I have a Sociology Degree. I suggest you drop sociology and take up nursing, it's what actually pays the bills for me.
So anyway Amy. Good luck to you. Hope you aren't still sitting at the kids table at Thanksgiving this year.
