Have a great deal of sympathy for most of what you say, arealthing, and know exactly what you mean when you talk about experiences on this site. The worst are the ones who start off as if they can make intellectual, or even emotional, connections with you, and the next thing you know, they get out their webcam to have a wank (metaphorically speaking, I'd never let them go there)
This is why I am attracted to women more. I don't have to do these emotional and intellectual cartwheels just to make some kind of vague online connection.
I am happy for a man to prove me wrong (like the one who's trying to do it now, with you, on this thread) but, after several weeks of talking to a range of guys on here, they seem incapable of just chatting normally as I find with women on lesbian sites. Not sure it's an age thing, I think it's a gender thing, unfortunately. And, yes, I hate that they take you for a fool when they try their little tricks. I too deliver on responsible jobs where good quality judgments are needed but it doesn't take much logic to work out just how many male profiles here are scams, liars and/or sex-obsessed.
I can't help thinking more of the older women on here would be happier with each other if they knew what's possible with other women
