How to increase husbands libido

So recently my husband and I were going through a lull with sex. We were lucky if we were in the mood once a month and have gone several months without sex

One big contributing factor for me was my weight. I gained about 50lbs over the past 5 years and I am disgusted with myself. Well long story short I am started to lose some weight, I don’t feel sexy yet, but damn am I horny.

My husband can’t keep up 😩 he says he needs to “recharge” but that was two days ago. I am begging for sex 2 times a day. How can I get him as horny as I am!?!?

And I refuse to dress sexy because I’m not sexy. I’m still very heavy and look awful. I know my weight is one of the biggest contributing factors to my husband’s lack of libido. I use to be skinny and really sexy, now I’m a potato lol but I will take any tips or ideas (other than dressing up)
