Boyfriend thinks our bedroom is dead

Hi,just wanted to vent. I’m 24F and my partner is 26M. I’d say our sex life is okay. We normally have sex 2-3 times a week when I’m not on my period but lately I’ve caught him on his sub reddit saving posts about the bedroom being dead and constantly feeding rejected. The reality is I’m not meaning to reject him but he only wants me when I’m actively doing something and I am like disgusting cleaning looking a mess. I want to feel pretty and put together and desired when he advances me. Not bleach or dirt covered or in the middle of 9000 tasks feeling like a rag when he does. I keep sharing this but it doesn’t seem to matter. He’s cheated on me 15 times,has a porn problem and I’m facing new health issues but I still make the time and effort but I truly don’t think I’m doing enough or just enough in general?? I’d never thought I’d be here going “is our bedroom really that dead???” He used to want me all the time when other women were behind closed doors and I wanted him too but between my health and hating myself it’s like?? How am I not doing enough in this circumstance?? Everyone on the posts said to just leave and stop being miserable for the ones feeling rejected but to be honest what about us drug through hell and back and still fighting and showing up to try and make sure their needs are met? I truly don’t know what more I can do?? Any advice??? I can’t be the only one feeling inadequate and taken by surprise on this side of-the coin..? I’ve tried to post about this before and it’s gotten taken down but I’m not sure why this side of the coin is so villainized m…at least that’s how it feels.
