My boyfriend is going to Ibiza. Should I be worried?

Me and my boyfriend have been going out for 10 months....we are madly in love and he makes me feel so happy and special. However, I am quite a paranoid and worried girlfriend. I do trust him but he is going with 10 of his friends and they're all single and 21. I'm so scared they make him go to strip clubs and nightclubs and they all meet girls. I know he would never cheat on me but if his friends meet a group of girls, my boyfriend might speak to some of them too and they might get worried. I am so terrified he cheats on me or he meets someone else while he is there. Can you please give me some advice? He promised me he wouldn't ever cheat on me.
