I tried having sex being a 15yr old.

me and my guy bsf starting dating few months back and its been amazing. we makeout regularly and its so good. he's patient amd always understands what I need in the moment.

recently, I invited him over and we had a crazy makeout sesh - I sucked his dick, he ate my pussy and sucked my tits and then we decided to have sex but like only for him to go in and out a few times so that he doesn't cum in me cuz we didn't have protection.

I got on top of him and was ready to lose my v card but then when he tried to put it in, it didn't go in. i tried to guide his dick inside aswell but it just didn't happen.

what should I do?

(p.s : I WILL BE GETTING PROTECTION NEXT TIME DW)
