I want to have hot sex again

I have been dating my boyfriend for a couple years. I feel like as far as sex goes hes pretty good, and it’s me that’s the problem. He’s definitely better than my last boyfriend and his dick is DEFINITELY longer. But lately I am not as turned on. When I spend the night with him he is turned on immediately (morning wood or whatever) and I’m just tired and want to lay there. He always is the one initiating sex. And he tries so hard to give me an organism, but it’s a lost cause honestly.

I just want to have hot sex again. Maybe it’s because our relationship isn’t as new as it used to be but I’m open to talking with my bf or experimenting if u have any suggestions.
