1) He's not a bachelor, so "sowing one's wild oats one last time" is not an option. That ship sailed long ago, and with two young kids is lucky to have any oats left (I would know).

2) He's already been in the relationship for two years. A bachelor party would not only be inappropriate, but could be hurtfull to the bride in my opinion. A guys night out could also be mistaken for something it's not, and would be best if just avoided I would think.
