I'm glad you are able to understand sex isn't just penetration. Your efforts to find stuff seems legit and balanced.
Maybe that should be classified as lewd scene instead of sex scene, since it could be confusing. Given the way the OP frased the question, I thought he already knew that there weren't anal sex scenes and didn't remember how to unlock the scenes we already have/wanted to know if he unlocked all the scenes we already have. In any case it doesn't make sense to discuss about it, since the OP wanted to know if there was an anal scene and I made the mistake of answering every lewd scene I knew.
