Need help not worrying about boyfriend's upcoming holiday

Hi everyone!

I think I just want some reassurance more than anything honestly. I have been dating this guy since November and we both stopped talking to other people pretty quickly, and he finally asked me to be his girlfriend last week! I really like him and I trust him as much as you can trust someone you've only known a few months, I just have had pretty bad experiences with dating and relationships before.

Yesterday we went out for Valentine's Day, and he told me he had booked a holiday with his friends to Morocco in July. I told him that's so cool and asked if it was a last minute thing since he hasn't mentioned it before, and he said they had spoke about it but only recently properly sorted plans out.

I'm just a bit worried because its him and 5 of his friends (all men), and I don't know what sort of stuff they will get up to so I keep imagining it to be a typical "lads holiday". I know he likes clubbing (so do I), but I've just heard so many stories of men getting drunk and cheating while on holiday and it's making me a bit anxious.

I was just wondering if I should ask him about it, or would that put him off me? My insecurity definitely played a part in my last relationship ending and I'm terrified of that happening again :(
