As a longtime DBer we used to talk about "overnight" guests a lot here. And what was best for the kids. It was generally agreed that 6 months was about right before MEETING the kids and only if there was long term potential. No "sleepovers" until after there was a commitment of some sort. How confusing for that poor little boy if he tries to get attached and suddenly Mom's new boyfriend is gone. He has already lost a dad.
I'd question any woman who was ok with having her son around when we had sex. That is simple. Call me a prude but protecting our children comes before any other needs. You get one shot to do it right and raising your kids on your own makes it twice as tough. Let's think about the little guy first. If you're not "into" him - forget her.
