As for everything else in life, I can only speak for myself. When I'm looking to sext and more polite than most of those rude people that you speak of however I think you adequately answer your question for me it is more about connecting with somebody the relationship between two people even if it is just for sex then just the sexting.
It is more important for me to make a connection with someone did have a brief relationship even though it pertains strictly to sexting it is better than being alone on a porn site although that is preferable to some of the assholes I've run across.
I hope this adequately answers part of your question.
if you would like further info or had more questions I'll be happy to discuss this with you.
Hit me up anytime I'm a real human being it's not just about the sex.
