I am 41 now. Dating in your 30's especially on those with kids/previous marriages/LTR's usually progresses to sex pretty damn fast. I personally didn't feel it really affected many of my relationships from going full-circle.
Even my ultra-conservative current wife and I ended up in bed around the 3-4th date. I was about 30 at the time, she was 40.
I will say that many guys that tried to hold the reins ended up not getting called back much and eventually ended up broken up with especially the guys that tell their chicks "I can't let you move this fast" and crap like that. Women don't want to be in bed with their father.
