I had anal sex for the first time in a while, and now it's been three days later and I still am not pooping. There was a little bit of pink at the time, but no real blood and I didn't bleed afterwards. I don't feel constipated, and while I'm sore/a little bit painful if I try to stretch myself down there, there's no pain otherwise. I am really gassy, and I'm worried because I usually go number 2 at least once a day.
