My wife basically wants me to beat her when we have sex when she’s drunk and I struggle with that. In particular she likes and wants me to choke her the fuck out to the point I swear I’m going to leave marks/bruising and she’s making noises that sound painful. It kills my boner tbh. Any advice on how to bring the aggression she wants? It was easier when we were younger, but now she’s the mother of my children and I just struggle to bring it like she wants.
