Okay, I think it's important to feel sexy and to think yourself as sexy, not just see your partner as attractive. The more practical obvious answer, if it's habitual, is to change your habits. Easy to say, I know.
Do you watch porn? If not, watch more porn. Explore what turns you on (and what doesn't). Conversely, do you watch too much porn? Is it an addiction that takes away from sexy times with your flesh and blood partner? If so, wean yourself off it in order to encourage you to scratch that itch with hubby.
Do you masterbate often? If not, masterbate more. Make some time for yourself and really feel around, get to know your body and your genitals, intimately. Know how and where you like to be touched. Same conversion as above applies.
Set a date night. You may hear things like "spontaneity is the key to passion!" However, there's strong evidence that scheduled sex (as unromantic as it sounds) is actually very heathly for married couples, and is very useful for keeping the passion going after years of familiarity. If you really commit to it, it can help reverse the habitual behaviour, get you both used to having sex together again. Sometimes we just have to remind ourselves - mind and body - that sex actually feels great and we do rather enjoy it. You may find that having a set time and/or place for sex helps build anticipation, something that can be aided and teased with cheeky texts, saucy notes, naughty pics, etc. There's nothing that says you have to always do the same thing on date night (either in or out of the bedroom) - you can still aim for variety and surprises, etc. Which brings us to...
Try something new and exciting to help "kick-start" your desires. Get some new sexy lingerie to both titilate him and help yourself feel sexy again. Like you said toys may be helpful too. If you're both game, maybe you could even turn the lack of sexual contact to your advantage by taking date night one step further and roleplay some "met someone at the bar/hotel" routine - explore each other as if for the very first time. Again, pretending to be someone else for a night of passion is one way to regain that sense of spontaneity.
Finally, good old fashioned communication. Make sure you're both on the same page. Talk to him about your feelings, about your wishes to make things better again. Find out where he is, emotionally, psychologically. Hopefully, like you said, this is just a habitual thing, a classic case of becoming complacent with someone you see every single day. But even if there is any other issues, communication is key to finding a solution.
The very best of luck to you both!
