It's been a few months and this thread is still on my mind. I have some interesting numbers about me and my girl to share. It's been real fun, to be sure. I wish all data-gathering were this much fun 😀
She generally has her first orgasm between 60 and 100 strokes, depending on the day, but 80 really seems to be the magic number because at least 3 times she's cum on or around the 80th stroke. Once she came on the 40th stroke, we were doing it doggy and she'd initiated sex and was super horny. On the other end, one time it took her like 125 or so thrusts before she reached her first orgasm.
For me, I usually start feeling my orgasm start to build up around the 150th thrust or so but it varies, like if her pussy feels particularly good that day I might feel it building up earlier. I slow down to keep things under control, stopping briefly if I need to. She mostly likes shorter, quickie-type sessions, so let's say 200 to 300 thrusts maximum before I cum and we relax. But one night we had a ton of time and had been drinking and smoking, so we went slowly and I lost count after 500 thrusts, but we didn't go hugely longer than that.
Any body else been keeping track lately?
