He no longer finds me attractive 😞

There's something wrong! I guess I've gained to much weight for my husband and now he doesn't want to hardly have sex anymore. Here lately it's been dragging out till 1 month or over. I've been having to pleasure myself! I've been so unhappy with my weight gain but now I just feel really depressed about it 😞 I keep telling myself that I need to lose weight. Why is it okay for a man to gain weight but when a woman gains it's she becomes unattractive 😞 I'm just hurt. And when he finally wants to have sex I feel like he's held it as long as he could and finally needs the pleasure like it's hard for him to get turned on or something 🤷‍♀️ idk what to do besides lose the weight so we both will be happy.
