Husband has no interest in romance

Tonight I sent my husband naked pictures from the bathtub to try to initiate something and I got a “let’s make this quick” so I went to the bedroom turned on the fireplace setting on our smart tv and turned the lights out for some mood lighting. He came in got naked we had had 3-5 minute sex with basically no foreplay and then when he went to clean himself off he just casually brings up how we won’t be able to have sex much after I have this baby unless we use protection or I get my tubes tied. Which led to an argument about how I would prefer him to get “fixed” if we go that route and he said he doesn’t want to go through that pain... like I’m about to push out our second child from my vagina but you can’t get a tiny procedure done if you’re so worried about kids? Anyway I’m getting off track.

I miss when he actually gave a shit enough to set the mood and try new stuff. He literally asked me what position I wanna do and then we settled for missionary again. I want to spice it up but anytime I try it’s missionary for a few minutes I barely make it to an orgasm and then he’s back in the living room to play his video games and I can’t help but think he’s just not that into me anymore. Like am I not worth the effort anymore? I tried to talk to him before about it but then I felt guilty because he was upset I brought it up. I just feel gross and unwanted. Like when did sex with me become a chore to him? Was it all the weight I gained or just lack of interest.
