Long distance sex life advice

Kitten

So i’ve been dating my SO last may, we had sex for the first time in december and again in january, and didn’t get a chance to since the lockdown began because his work and my class schedule. When the quarantine began we quarantined separately because he is an essential worker at a super market and he always made sure my family and i had anything we needed. Since the rates went back up my mom has been extremely paranoid about me leaving home to go see him at work or even goto his house. Lately i feel that he’s becoming less attracted to me and finds me boring , i need advice please. i really really want to save my relationship.
