Scared to lose my V card

Hi ! I'm 17 my boyfriend is 18 we've waited for such a long time to have sex and today I invited him over since no one was home and I thought I was ready but I WASNT. Just him putting his finger in me hurt like a bitch . We ended up not having sex and I gave him a blowjob to makeup for it . I thought I was ready and I was even excited but I guess not because I was LEGIT scared for him to put his dick in me. It has to happen soon , but the next time I want to be completely ready . Any tips to ease my nerves?
