How I can keep my butt from being violated during my marriage ceremony?

I’ll keep it short, It’s very common in my country for guys to grab the groom’s butt during his marriage ceremony, and I’m already getting butt-threats.

People suggested different stuff, but never anything feasible. I’m currently looking at skateboarding padded shorts, maybe have my tailor take measurements with those in account.

Any well-intended advice appreciated, I don’t do these things, and I don’t like them done to me. Sucks to have my pride hurt on my big day.

I didn’t where else to ask, Thanks in advance.

Edit: I spent over 30mins writing replies. I’ll continue later.
