ok. so, tmi.... my bf and I have attempted to have sex since my c section but we have to stop every time because before he can even get halfway in i have this burning sensation so bad that we can't continue. has anyone else experienced this? does it get better? is there anything that can be done to help with the burning? I hate not being able to be intimate with my bf.
