Posting here for traffic, sorry if TMI!
While pregnant I did kegels and perineum massage fairly regularly and was lucky to give birth with no tears or cuts.
However, sex is still painful 7 months on; not excruciating but enough to make penetration difficult and make me wince throughout. It feels like everything is a lot tighter up there but not in a good way!
At my 6-week check-up, the gynaecologist inserted the speculum and it was very uncomfortable, which it had never been before, and he said it was normal to be dry after childbirth due to hormones and BFing. But I'm not actually dry down there at all! Even so, I've tried using loads of lubricant during sex but it makes no difference because the pain isn't a dry pain but a tight pain.
I used to swear by my mooncup but even inserting/removing that hurts 
My period came back a few months ago which I hoped meant that I'd get back on track but I'm no better now than 6 weeks postpartum.
Has anyone been through something similar? When can I expect it to get better or are my days of enjoyable sex behind me??
