I don't really see how HD/HD and LD/LD only marriage would work. We know, do we not, that newer relationships basically cause LD people to experience a hormone rush and become HD for awhile? For the most part, I don't see how you'd figure it out.
On the other hand, I was in a relationship with my wife for four years before we were married, and looking back I realize that she was in that HD stage for about two years and then LD for 1-2 years before we got married. But at the time, I was young and dumb and chalked it up to other things. When we met, I was a virgin and she was . . . not. On our first date, we walked and talked all night, went back to her room, and found her roommate very busy with some guy, so she came back to my room. She slept on my bed in my dorm room and I slept on a couch. She was either very trusting or very open-minded, but we kept it to a kiss. I made her wait a lot longer than she wanted for sex (ironic, huh?) telling her I wanted to be sure. When we did it, it was glorious, and she couldn't get enough. But eventually, other things got in the way, to the point that by our senior year I asked whether things would change when we got married. She told me honestly that she didn't know (well, ask a dumb question, get no answer.)
We really thought it was the pressure of living apart, doing student-teaching, trying to graduate, wondering where and how we would live, that was doing us in. And we still loved to do everything else together. I knew I was unhappy about the lack of sex, but it seemed selfish, like I was whining about a small thing. So we married anyway.
