What really bothers me sometime, that not every woman/girl can do it too. For sexting or sex talk, you need to have a really good fantasy,you need to be creative too. A lot of women/girls here, with which I was "sexting", wanted only quick fun.
Well, I like from time to time quick too, but in real. And in sexting? Give it a time, write it exactly as you would be there with that person, and of course try to give "a look" in someone's head. Creativity, imagination, fantasy - that's all what you need in those kinda talk.
And I hate, when you're in the middle of that conversation, and the other person leaves, or get disconnected. That's why, I'm not doing any "sex talk" or "sexting" on the chat anymore.
