Virginity

I'm going to Australia to do a 4 months exchange program this year and I'm 15. I wanted to lose my virginity with my ex bf( which I hated until I broke up with him- apparently, I'm those who wants sth just cuz I don't have it) but we're not togheter anymore. So, all of my friends keep telling me to find a guy while I'm traveling and do it w/ him so when I come back and do it with someone else it would not be a problem anymore. I actually have a desire for that and kinda liked the idea, but I'm so emotional and I'm afraid to mess everything up. What should I do?
