He's tearing my vagina!

This guy I've been talking to is on the bigger side (long AND wide) and I bleed after sex when I wipe myself off almost every time now! Don't get me wrong, the sex is AMAZING and I get VERY wet, but the first 2 strokes are so painful like my vagina is tearing every time. After a few strokes, the pain goes away. He is always gentle and slow putting it in, but it hurts regardless. Anyone have tips or experience the same thing??
