Boyfriend doesn’t wanna have sex

Soooo and my boyfriend lost are virginity’s to each other and ever since then he doesn’t wanna have sex again. Like I get it but I’m confused, most guys wanna have it all the time but maybe that’s just i the movies. Before we did he was always so sexual and talked about it all the time and now he doesn’t even flirt or tease me. I don’t know if I should feel used because I know he still cares about me but he doesn’t seem to as much. I don’t wanna break up with him either because as I said, I know he still cares, it’s just different now. I don’t necessarily want sex, I just want affection. What should I do?
