TMI Anyone experience this?

I'm almost 3 months PP. I had a 9 pound 5 oz baby boy. First degree tears. I was pretty badly swollen. Due to the tears and small cuts when I urinated I had to come home with catheter because of pain. I've tried to have intercourse a few times now. It's still painful and almost feels like there's scar tissue. We've tried using lube but doesn't seem to help much. Has anyone expirenced this or have any ideas how to help ease the pain?
