sex after giving birth...

Ashlee
I've just had my 4th baby 4 weeks ago... 
Tonight me & my partner had sex for the first time since giving birth... 
I did not enjoy it at all.. & I could tell my SO didn't either!! I felt soooo loose down their it literally made me cry! 
Has anyone on here had any treatment either surgical or non surgical to fix this problem?? & yes I do my pelvic floor exercises every day.
