Sex tip for first time

Me and my boyfriend have decided that we both want to have sex during the upcoming school holidays. We both are virgins so we don't have much experience. Is there a trips that I could know forth the first time. And as for condoms is it likely that they will break? Is there anything I should know. ?? Thank you and please ANWSER with anything remotely useful. I would really like to know ❤️❤️
