Sex after birth and breastfeeding?

Christa.

So my husband and I have tried to have sex post birth while I am breastfeeding. I know they say breastfeeding is natural birth control and that you can get dry but when should I be concerned? We tried for like the third or fourth time to have sex tonight and I feel like my vagina is broken. I will be wet, enough where he can finger me and get me to orgasm but I literally cannot fit his penis in me. I would say he is average size so it would not be size I’m not sure what’s going on. They did have to stitch me but it is well past my 6 week visit and everything was good to go according to my doctor. Everything worked just fine before my daughter. What could it be? Anyone with a similar experience? Would this warrant another visit to my doctor to double check my status? Please help!
