Oh goodness...I feel like sex is just inherently full of opportunities for awkwardness. It's good to be real about them!
#6, though. I hope you don't feel bad because you didn't want anal play and the guy you were with did. Even if you've changed your mind about it now, you didn't want it at the time, and he should've respected your wishes. It's your body and nobody else is ever entitled to it! I'm glad you said something to him.
