No you aren't expecting too much. If it's something that you feel you need to talk about, bring it up to him. Let him know you would like to have some conversation about it, and be prepared with a few things to say on the topic. How it felt, what you liked and disliked, and whether you would like to do it again, and what you might add, as a few topics. Because if you say, "I'd like to talk about the scene we had" he'll probably reply with something like "What do you want to talk about?" In my experience when dealing with men in general *grins* just have a few things you'd like to talk about to help get the conversation rolling. Once it's going, it's often easy to just flow with it and express feelings.

In any relationship communication is very important. However, with D/s couples I think the communication can be even more important. Especially when dealing with feelings about a scene. There are so many emotions that are involved, you never know what might creep up.

So, don't be apprehensive about bringing up a topic. Just let him know you'd like to chat. I share all my feelings with my Master, both good and bad. Anything from my joys to my being REALLY pissed off at him. The best part... he listens! Talk to your Dom, this is something that is obviously nagging at you. There is nothing to fear in sharing your feelings with him.
