As a young man and when I didn't lose two inches to pubic fat, I was quite proud of my length. Yet, a few women complained that I went too deep. For example, one was only a little over five-feet tall, and another was Japanese-American. When I met first wife, who was neither short nor Asian, she made no complaints—at first. Her actual complaint was that her lower back hurt after we fucked. I assumed that I was putting too much weight on her, so we tried several sex positions other than missionary, such as doggie and cowgirl. This made matters only worse. She went to the doctor and was told that I was pushing against her cervix, which then pushed against her tailbone. I tried to limit my strokes, but I mostly failed.
One day, we were at friend's house and she spotted a toy bagel made of soft rubber. On the way home, we stopped at several toy stores until she found the bagel, which I dutifully wore when we fucked, which was daily and many times on the weekend days. Over time, say, half a year, the need for the rubber bagel vanished, as her body seemed to have altered its internal geometry.
When we began sharing her body with other men, the first guys were all smaller than me. But that changed with my close friend Michael. The lower backaches were back. Then, a few months later, they vanished as before. A few years later, much to our surprise, our otherwise lame neighbor released the largest penis she had ever encountered. Too big to even fit in her mouth. When he walked about with an erection, his cock bobbed and swayed like a long two-by-four being carried on a carpenter's shoulders. We braced ourselves for the looming lower backaches. None. She received his entire length and, amazingly enough, was not hurt by the length. His girth, on the other hand, took some getting used to; in fact, she called being fucked by him as "pussy stretching time." (His cock was flat and wide, not round.)
After we divorced, I discovered that if I didn't fuck porn-movie style, but instead (after insertion) made only circular grinding movement, my cock deep inside, with no banging, women were having cervix orgasms from my cock sliding around their cervixes, rubbing against their anterior fornix erogenous zone. They told me that where their clitoral orgasms were sharp and brief, the cervix orgasms were diffuse and prolonged, radiating out from their vaginas up and down their bodies.
Actually, I didn't so much discover this as lift from a girlfriend who was the most vaginally orgasmic woman I have ever known. She would ride me cowgirl and orgasm hugely. She didn't pound me, but circularly grinded on my cock. I wondered if I could not do the same to her with me on top. It worked.
