I don't think my boyfriend is attracted to me anymore...

I've been sending him sexy snapchats and he never responds. Last night, we were both naked in bed and I was practically begging for it... I would scoot closer to him, play with my boobs, kiss him and he didn't react at all.... He didn't even get hard and he always does when I do that. I've also been suggesting new things like trying out some toys, new positions, etc and he said he's indifferent... Every time I would turn over naked and show off my body to him casually, he would just turn over and cover up.... I just feel so ugly now and that he's not attracted to me anymore... It's been like this for a couple of weeks... Even when we have sex, it's the not the same anymore... Idk what I should do/say... Or am I just overreacting.... Any sort of advice would help
