Feeling neglected

✨Izzi✨ • in a relationship // plan to be child free.
My SO and I used to have sex like bunnies, up to 6 times a day! But now 5 months in its slowing down, to the point where it can be 3-4 days with nothing. He often says he's tired or just wants to cuddle and that's totally okay, but I can't help but feel like he's not attracted to me, or what ever. Like last night we went out for a lovely meal and when we got in and went to the bed room he helped me take my dress off so I was in my corset and matching bra and panties and then he just said "do you want to see what's on Netflix?" 
Like sometimes it's like he doesn't even look at me or realise how much effort I'm putting in. 
I told him this morning that I worry he's not attracted to me anymore and he said sorry, and that he will compliment me more but that's not the point? I don't care about his words I care about his actions. 
Am I being irrational??
