Boyfriend going on lads holiday?

My boyfriends just told me he's decided to go t Magaluf for 2 weeks with his friends on a lads holiday and its all paid for to go. Although I trust him and he's never cheated on me, I don't trust his friends as they cheat on their girlfriends wherever they go and I really don't want my boyfriend to go with them, am I right to feel like this? what should I do?

hes also cancelled our couple holiday we had booked because his magaluf holiday clashes, but said he would re book for another time
