I need advice 😅

Al🦋

I’ve been put on the birth control pill and I start taking it tomorrow . My current boyfriend and I want to have sex (both of us are ready to ) I’m a virgin and he’s not which is totally fine but I’m terrified! How long should I wait until we go at it ? I definitely do NOT want to be pregnant . What should I expect or do for the first time? I just need advice for everything so someone please help!!!
