Boyfriend w low sex drive

My boyfriend and I have been together for a year and a half. We used to have sex twice a day. Now we don’t even have sex once a week. I know for some couples this might be normal. But I’m a very passionate person in all aspects of my relationship. I am still very attracted to my boyfriend, I still feel exactly the same as I did in the beginning of our relationship. So for me I want to have sex every day (or more than once a day). And not just before bed, but spontaneously. I’ve talked to him about it several times to the point where it just frustrates him now. Sometimes he’s understanding and says that he’s just “gotten lazy” and other times he just gets mad and says all I want is sex and he just doesn’t. I feel like something is wrong with me, I feel so ugly and unwanted. I’ve gotten paranoid thinking he’s maybe talking to someone else or maybe just in love with someone else (because he literally would have no time to physically cheat on me). Maybe he’s watching porn and jerking of all the time, or maybe he’s even gay. I don’t know what to think anymore. Our relationship is just getting worse and it’s not just because of the lack of sex, there’s hardly anything good left in our relationship. He says he’s in love with me but he doesn’t act like it at all. I love him so much but I desperately want our sex life to be better, I want to feel wanted and pretty again. Is anyone else dealing with this? I need some advice, ladies. Please no negative or rude comments. We’re all here to support each other not make each other feel bad about our personal problems. Thanks!
