How have the dommes or the subs on this site handled these types of relationships? Should i back off? see her less? send her less? Or just keep doing what i am doing and stop worrying?
My solution to these types of problems probably falls under the category of: That's so crazy, it just might work!
When I'm not sure how she'll take my gestures of affection and devotion, I just ask her. Am I texting too often? Is it okay to get you gifts? Is it okay for the gifts to be romantic or personal, or should we keep to sexy dominatrix clothes and whatever is on your wish list? I've gone all the way to: can I tell you I love you?
Presumably, you picked her as your first regular mistress ever, because you have a connection with her. She may well feel that connection too, so there's absolutely no reason to sit and guess about whether you're making her uncomfortable, or on the other hand, guess that you should dial it back (and potentially leave her wondering what she did wrong when she notices you withdrawing). Just talk to her. In fact, if you talk to her about things, you might find that there might have been something that made her a little uncomfortable, but the mere fact that you showed the concern and self-awareness to communicate with her about it, allays her concern.
In short, no drama, no complexity, keep things easy between you, just talk.
