S.O.S

A
so my boyfriend and I have been dating for almost 3 years now. He is the first guy I have ever fallen in love with. we are pretty comfortable around eachother. A little while ago we decided that we'd try to have sex. we have been foolin around for a few months now with other other things 😋 but we really wanted to see what it's like actually have sex.  
so the other day I went over to his house. we ended up making out then things got pretty heated up. I wasn't expecting to do it that day but it got pretty intense. so we tried to put it in but...IT WOULD NOT GO IN. i tried about 3 times. (and yes i was very wet) i felt so embarrassed and i felt like i ruined the entire mood. so i got off of him and we got dressed 😔... 
i need advice
