Protected sex problem

Last night I was trying to have sex with someone Ik and trust. Yes we used a condom. But every time he went in, he was slipping out. At first it was because I was wet and then I pushing him out. 🤷🏽‍♀️ ig it was because my pelvis wasn’t relaxed enough or couldn’t take him in. But when he fingered me, that was the only thing that could work. Lastly it was slightly uncomfortable. Is that normal ? Matter of fact, is all of this normal? The dick can’t fully go in because of my pelvic floor not opening or whatever and having a small discomfort. So is all of this really okay 🤷🏽‍♀️
