Did I just experience pity sex/obligatory sex from my husband?

I (32F) and my husband (32M) have been having issues in the bedroom since being married (7 years). My husband has a history of being a heavy porn user and there have been lots of moments where we would only have sex once a month if I initiated. Also plenty of other moments where he would go limp half way through sex.

Anyway, a couple months ago I found out he was masterbating to instagram models daily without my knowledge in the bathroom. We had a big talk and I expressed my desire to be more intimate with him and the importance of me feeling like he’s choosing me over his phone screen.

Last night…. I was totally in the mood to have sex with him. After having a great conversation about our day he suddenly went quiet for a good 5-10minutes so then I rolled over and said good night to him. I was waiting for him to initiate because quite frankly, I’m tired of feeling like I’m the only one desiring him. He put his shirt on and said good night. I said “wow so you’re not in the mood?” He said no I’m not. I asked him why he said that throughout the conversation we were having I gave him lots of attitude which is ‘not sexy’. This completely through me off guard as I never spoke to him in such a tone and believed our conversation was great! I expressed my opinion and frustration. I told him I think you are just looking for an excuse not too and it’s ok… after he realised how upset I was he then started touching me and having sex with me.

After the whole ordeal I felt like absolute rubbish… I should’ve just let it be. I forced him to desire me or he slept with me so I don’t sit there nagging him. This is the first time I ever feel this way… so was this pity sex from his part? He apologised after it saying I’m sorry I upset you and I love you but I just didn’t have a bar of it. Something just didn’t feel right. I feel like I’m the only one chasing, initiating.

Would love some insight from both husbands and wives.
