Scared and worried about sex

So me and my boyfriend have been talking about having sex and my birthday is this Thursday and we both have the day off and some times before we go hangout with some friends and well he said if I wanted to have sex and I said yes but now as it gets closer I’m scared plus I’m not on birth control and we want to do it without a condom and like what if I’m not good or I don’t know what to do or what if he doesn’t pull out in time and he cums inside me can I just take plan b? I’m just nervous and what if I don’t please him or I don’t moan or something why is sex so scary when I love him and I do want to do it?
