Both the men I've had sex with since my separation were intelligent, attractive, very affectionate, romantic and comfortable with their sexuality. They both had careers with solid "purpose" and actually even hobbies with "purpose" too, cultural and political believes largely in alignment with mine and responsibly maintained households. They both actively pursued dating me and there was nothing in their behavior towards me that was in any way ill-mannered, quite the opposite in fact.
Call me dense but I don't really see anything "wrong" here. You had hot sex with a cute guy or two. Some people never get hot sex, ever. You're a "favourite of fortune", to quote J.A., both for being able to give and to receive. You're young, healthy, and there are tons of cool guys out there. Celebrate it.
Sure you and NG might have made a great long-term couple "if" you'd met him later blah blah blah. Maybe not. Maybe it all happend just the way it had to. It was gutsy to pick yourself up like that after Stbx imploded, and go out there. I like it.
My cat is watching it all from the couch, eyes lazily drawn to a slit, but in an approving way. *g*
