spara,
Welcome to HealingWell. May I ask what it is that bothers you about the bachelor parties the most? I also am not sure what happens these days at bachelorette parties - so perhaps if you could explain what you fear most a bit it would help.
Men have been having bachelor parties for years and years. If you trust him there is no need to worry. Its completely normal to express your feelings to him on the matter and I am sure he will come through on making you feel better about the idea. Once you have shared your feelings than you will need to put your fears into perspective and move forward with the joy of planning and enjoying your own wedding.
Once you are married there will be many times your own insecurities will make you anxious but remember in the real world you cannot be together 24/7 so you will have to increase your trust in him as living in fear will drive a wedge between you.
Remember he chose you, you chose him for certain reasons and hopefully building a trusting relationship will continue all of your married years.
Congratulations on your upcoming wedding.
Blessings,
Kitt
