How should i respond to his text???

Ive kinda posted about this already, but last night i sent my bf a few sentences about our sex life and the problems we have with it. We were chatting on the phone prior, and he just hung up. He responded saying hes tired and that he loves me. He texted me this morning good morning beautiful, and i responded good morning. And now hes texting me like nothing happened. Im still upset about our conversation last night. So i havent responded to his text. I know we will get through it. But i cant get myself to respond to his texts and be fake when somethings bothering me. I also know that id rather talk about our problems in person. So its not like i want to text anout it right now, but shouldnt he care or know that this is really bothering me? Part of what i texted last might is that i wish he would be honest with his feelings more, and then he said hes tired and he loves me. So how do i tell him this? I am annoyed he doesnt want to talk about this. It doesnt have to be right away, but at least acknowledge that we need to talk about it sometime soon. You know? (Btw the issue was that he gets defensive and annoyed that i haven’t been able to orgasm during sex with him yet)
