So last week I went relatively hard with a couple of 2.5" diameter toys, my it was only my second time ever going that wide, and my ass was literally sore, the anus for obvious reasons, but also my tailbone area. so much so I couldn't sit for the first day. Two days later once I thought I had recovered I took a 1.5" dildo and went really hard and fast for about 10 minutes while trying pushing my rectum out against it, it felt awesome, but then, for almost 48 hours the tailbone area was extremely sore. I'm healthy and strong and there is nothing wrong with my bones or joints, it's just that the intense play seems to tire some muscles that I can't pinpoint, am I right? has anyone else experienced this? what is it?
