Boyfriend [30 M] is sour about me [29 F] going on vacation with my girlfriends

tl;dr We have been together for five and a half years. I've never taken a vacation with my girlfriends. I'm going to Tulum and Cancun and my boyfriend has a "bad feeling" inside about it (as he expresses to me). It's my best friends 30th birthday and we will be spending New Years there. He basically has it in his head that all girls go "girls gone wild" when on vacation together.
Instead of being happy for me or wishing me a good trip, my boyfriend [30 M] is pouting and expressing how much he is tortured by the idea that I'm [20 F] going to be in Cancun for New Year's Eve and for my best friend's 30th birthday (we have been friends for 20 years). It will be four of us girls in an air b&b and I was (and still am) so excited. I've never gone on a trip with my friends like this (only within Canada and ten years ago). However, his attitude has already put a cloud over this trip, which is a month from now.
Meanwhile, my boyfriend will be spending Christmas with his family in another province. He is going for over a month. While he is there, he will be taking a trip to the U.S. with 5 of his guy pals to go watch a basketball game. I'm fine with that. I'm happy for him. I tried to reason with his agitation by saying that I trust him going on a trip with his friends. He said it's completely different since he is going with his friends to go watch a basketball game. I guess his point is that his trip has a wholesome purpose, while mine does not.
I believe his attitude is hypocritical, selfish, and somewhat demeaning and controlling. I think it's childish and it's giving me a lot of anxiety. I already know I will have to go out of my way to check in with him, which is embarrassing.
Btw, I am not going to Cancun to get wrecked etc. My friends and I are looking forward to outings and day trips to see beautiful sights etc.
Also, my boyfriend has always had trust issues and I have honestly not gone places before just to avoid reactions like this.
Is this normal behaviour? Has anyone else been in similar situations? What would you do?
