This is something that i used as a newbie here guys
Here is 1 simple techniques you can use two bring sex into the conversation while on the phone.(BOTH TEXTING AND CALLING)
1. Ask her to rate herself on how adventurous she is or how much of a risk taker she is on a scale of 1 to 10
Usually its above 5 if not you can tease her about it
Then say this "Hey i have to tell you this totally Shocking thing that happened to a friend of mine he was watching porn at his place and of course masterbutatin when his mom wasn't there but the Douche left the door unlocked guess what happened(SHEL BE LIKE "SOMEONE ENTERED or YOU TELL ME) Then you say " His mum came in !!!(Shell say "OMG OR SOMETHING" then you say it gets worse He let his colors fly (Or simply he ejaculated ) then you can say "We have "ALL" watched porn at some stage but at least have the sense not to get caught and i bet you can handle the conversation from there
then you can start talkin bout all the sexual shit :p
