losing virginity advice

hey, so I’m pretty inexperienced when it comes to this sorta thing so bare with me (😂).

basically today my boyfriend and I tried having sex and well... it didn’t really go to plan. everything was fine at first and stuff like that but when he tried to ‘put it in’ it just, didn’t go? like he genuinely could not get his dick inside me (if this is tmi I’m sorry).

idk if there’s anything I can do to make it easier as I’m just unsure of what I could do? it wasn’t embarrassing or anything as we are 100% comfortable with each other so it wasn’t a problem that we ‘couldn’t do it’, but it’d be nice for next time to know if we could do anything to make it work?
