In my sitch, DID do snooping ( and I don't think it was fusion) but came up empty handed. GEL, I should have hired you! I am now getting the cleaned up, G rated version of what went on with my H, and I am trying really hard not to obsess.
Karen, you are on the right track with the " just have fun" idea. I think your H has some high expectations of himself, and high anxiety, so doing what's familiar and staying in his comfort zone is the easy way out. I wonder if he has some solo activity he's doing...it's a lot easier too.
But enough of sex talk...soon you will have a bouncing baby boy...how absolutely wonderful!
