I'm so annoyed with my SO

Okay, my SO and I like trying new things in the bedroom. I'm just gonna say it, he enjoys being tied up, me being in control. We've done it probably 6 times since we've been dating and we've been dating for 2.5 years. He wanted to do this today, and then later tonight FINALLY let me be tied up for my first time. He got soooo upset with me for telling him that I would rather go first, that he actually told me he doesn't want sex today at all now. I tried to explain to him that I do not understand what the problem is, because if we were both going to get tied up today, and he's already experienced it several times, I think it's completely justified for me to want to go first. I just said okay and walked out of the bedroom.

He just now texted me as I'm writing this. He said, "I wanted to go first because I'm tired rn. That way after I can nap and I'd have more energy for you later".

Now I don't know how to feel. Mood is definitely killed for me now.
