It hurts to have sex with my current partner, it feels like a stabbing pain and I can’t figure out if it’s because the shape of his dick or because he’s a little rough and being forceful?

With the guy before him, it hurt a little our first few times but it was bearable, he did however have a softer/rounded tip whereas my current partner is a little pointy, if that makes sense? My current partner is slightly bigger in size, the tip is narrow and it gets thicker in the middle but we can’t even get it in?
