anytime I turn the texts sexual i stop getting responses. wtf is up with this!? it funny and not creepy i dont get it

It's creepy, and not funny. If it was the other way around, you'd be getting responses.

I get girls to get sexual in text all the time. Here's my rule for how I make it happen: if you haven't been sexual in the real world yet, she has to be the first one to get sexual in text, otherwise you'll come across as a creeper. This doesn't mean you can't walk her into getting sexual over text first, but you can't say anything sexual until she does. An example:

Me: Well, I'm going to sleep now. So unless you're coming over so we can have a slumber party in my matching pokemon pajamas you need to stop texting me :p

Notice it's not sexual, but there are some underlying sexual tones about her coming over and spending the night. It's funny and playful and gives her a window to respond with something sexual. If she's reached that point of comfort where she's entertaining the idea of having sex with you she may respond in a more sexual tone since you gave her an opening. This is much more powerful than simply saying "I'm going to sleep now, so unless you're coming over so we can have crazy monkey sex you need to stop texting me."
