Is 15 Times a Week Far Fetched In the Early Stages Of a Relationship? No.
I'm surprised at the Luncefords answering only twice a week. Newlyweds are often still in the "daily zone" and twice a day isn't far fetched ESPECIALLY if they're trying to conceive. Twice a week isn't bad, but that's pretty much on par with couples who've been together a whole lot longer and who either already have children or who aren't actively trying to have any.
If they tried 15 times a week (or even 7), they may have a better chance. I'm just saying.
It said a lot that Lateasha thought 15 times a week was a lie when it's common for couples who are early in the love stage not to be able to keep their hands off of each other. Doesn't sound like her and Gregory were ever at that stage.
