You will not hurt him. I was nearly 200lbs heavier than you are now and I've never injured a man that way!
As for jiggles and confidence? I promise he won't be looking at rolls or jiggles. His focus will be on your face and your mammary area

If you're still horribly uncomfortable at the thought, put on your best dress, the one you feel sexiest in and just leave it on. You're covered, you look good, and you're having fun.
Don't let this hold you back. You need to be proud of how far your body has come, and know your boyfriend wants you, jiggles and all.
