Ok so I got this girl warmed up. Her body language and the fact that she laughs at everything I say gives it away. I just met her for like 20 minutes mind you but I didn't let her know I'm interested in anyway, I just like to have fun. So when I text her but I feel like I take too long and there's not a lot of room for banter. For example, she says she wants me to send her some hw. So I tease her about it and she invited me to study, which is a plus but it took long and I don't know how she felt. I want to let her know I want to have fun sexually with her but it's difficult for me to do that through text (I feel like I have to sound fancy and impress). Thoughts/advice/ideas are appreciated. Thanks.

Edit: What I want to know is how to get better engaged at texting. We all have to text so how do you go about having fun with it. It's like chores, ya feel me? You have to deal with it but some do it right and others get the plates dirty.
