he wants sex.. 😭

I miss having sex with my husband. i miss feeling close to him. we have an intimate relationship in other ways, but I do miss sex. BUT, when he does actually want to have sex, he wants it when my hairs a mess and not washed, when I'm in my dressing gown and not even had time to brush my teeth! I don't feel sexy and I can't get in the mood, so I turn him away and make all sorts of excuses, & to be honest, I do even tell him sometimes the true reason why, but he just has his 'boyish grin' and still tries to have sex with me. it just doesn't interest me. I will say to him, 'baby, later; let me sort myself out first'. He says he doesn't care, I'm beautiful and he wants me. etc. etc. then its the same again in another weeks time when he tries again!! suggestions?? 😣 *my point is, he wants me when I feel my most unattractive! when I feel good, and sexy, he's always 'too tired, or busy'.*
