Is this normal?

My boyfriend / baby dad said that my vagina is tighter than it was before I was pregnant.. I’m 4 months pp and first time I had sex was like 5 weeks pp and it hurt so bad I gave up well now it still hurts when he first goes in but once it’s in it feels good but it’s literally never hurt before to have sex and I use lube before to help “entry” be easier but it still hurts a little but not too bad I’ve just never heard of being tighter after having a baby. I refused episiotomy because… ouch. Cuz I heard natural tearing heals faster and easier but I did get 2nd degree tears and I tore down and sideways (left labia) so I got like 3 or 4 stitches and they healed fine.
