Does he not find me attractive anymore?

My bf and i have been together for almost two years. The last time he asked for any “sex photos” or the last time we had a sexy conversation over the phone was in april. Then we stopped and haven’t done it since then. He went back home and has been gone for a month and well he has yet to send anything or you know.. sext me. I have asked a few tomes and he says yes but nothing happens later on. I also recently found out he had paid for multiple onlyfans subscriptions shortly after we stopped sexting whenever we weren’t together for long periods of times. He has since stopped and we have had a discussion about how im not comfortable. I used to feel so so beautiful and confident and now i dont feel like that. I love him a lot but he himself kind of lost himself and idk if hes just projecting his own insecurities and its rubbing off on me or if hes just not as sexually attracted to me? He promises he is but idk. I am tired of feeling so inferior and insecure when i used to be so confident and independent. I used to always be the bigger person and just loved myself entirely and have since lost that. Whats happening? Am i overthinking?
