<human>: Give me the gist of the text in a nutshell

I haven't read it yet, but I'm not even sure if its appropriate to talk to my best girl about it (don't want to break trust or anything- thus I'm turning to you guys!), but he told me this morning to come over tonight at 7pm, sharp, and he'd email me with the rest later. 

Well I've got the email, but haven't opened it, because it kinda feels like a christian grey type thing.. but I'm not into that really. Though he's not been like that before, and I'm not sure that's even really what this is yet.. 
I'm open to things sortof, but I've been at work all day & not really up for this today. I want to tell him I don't want to have sex tonight. I appreciate the thought and all. 
 
I'll check the email & get an update soon..
<bot>: Boyfriend has instructions for the evening, I'm wondering if I should just go with it, or speak my feelings..
