I love that post. I'm 5'71/2" as I always strived in the same way. These days I don't even bother I claim 5 feet 7 inches and done with it. During my travelling days it depended on where my partners came from. In most of S.E.Asia the women were generally shorter that me apart from 1 lady who was about the same height, it was only the heels that made a difference. But in Africa or the middle east I had a couple of African girlfriends who were much taller. One that I wrote about in my Desert Loves book was about 6'2" and with her massive Afro hair and heels she towered over me and we walked out as you described. We have met up in at least 4 different countries and some places did receive strange looks, but we are good in each other's company and the sex is always great.
As you describe the 69 was awkward at first but we made it work well by adding a bit of pillow height for my head. She had massively heavy boobs also, very solid, not flapping, and she knew how to use them. She would tit-fuck and blow me with abandon and was one of the best at it. Missionary, was always good, probably better than with someone more my size, and doggy was good but I'd have to virtually stand or she would lay flat and it would be heavenly.
We have always been good together and even walking apart at the Mall I would often get horny just being with her. The thoughts of her BJ's was always enough.
These days I'm too old to let a thing like height compatibility interfere with such an important thing like making love. Good on yer also.
