What was your best birthday sex? Mine was a few years ago. I spent most of the day in bed enjoying sex with three women. I got some alone time with each of my two long term partners. I had some lovely romantic wake-up sex with one of them. By mid day, I got in some vigorous sex with the other. In mid afternoon, a friend came over to visit and she and I spent about an hour having one-on-one sex. After a dinner with all of them, I got a threesome in the evening with my two regular partners.
