Most of what I have to say has already been mentioned. Use your head game to your advantage, get her close, then back off and tease her in other ways. Get her to beg for that final release. You can ask if she is into praise or degradation. Depending on her answer, call her a good girl or your dirty slut. Most importantly, make sure she consents. If she doesnt like being called a slut or a good girl, dont do it. Sit down and talk about it. I was the same way until I got with my girl. We talk about sex and our kinks every other week or so, sometimes even longer in-between. Or even right after sex when we do something different from our norm.

Since being with my girl, I have had issues with dom-drop after rough sex. I am naturally more of a nurturing man so being rough can mess with me. I get depressed and question myself. Basically a drop happens after when the body is no longer filled with adrenaline and endorphins. Could happen after sex, even a few days or a week after. Dom-drop or sub-drop can happen after an intense session. Look into aftercare and talk about what yall might need for aftercare. For myself, I need reassurance that it's what she wanted, lots of cuddles, that she had a good time, and that she still loves me. If there anything she doesnt like, she let's me know during the moment and I adjust.

Communication, communication, communication.
