Emotional after the deed

My husband is very respectful when it comes to our intimate life. We have had anal sex a few times, but always at my request. He’s never asked. I actually find it quite pleasurable in the moment. However, after we’re done, I feel disconnected and used despite being the one who asks and even wants it. Those after feelings have consistently gotten worse. I think tonight was the last time I’ll suggest the activity. I am just wondering if anyone has insight into why this is the case? Also, has anyone experienced something similar?
