How do I handle/hold myself when the girl is very forward and direct. I can see that essentially she wants me to take the lead and direct our sexual interactions. I'm honestly still very inexperienced and unconfident at this.

Context: I've already slept with her once before, but didn't contact her after. Saw her again at a party and hooked up with her. Received this message today.

"Her: You fucked me in my dream last night, it's safe to say I woke up incredibly horny today..."

Seriously, how do you respond to this? I can't see her until the weekend. So logistically it's not an option to invite her over now. What's the next approach?

Basically, how do I grab my balls and handle properly?
