Thanks Taz. Yes will go to GP. This one I have now is quite sympathetic.
When I think back, discomfort after intercourse was sometimes an issue before my relationship broke up. GP then informed me that I was traumatised by the fast birth of my daughter. Didn't matter how much I told her I REALLY wasn't - in fact given my dread of childbirth, the experience was really OK and a great epidural was swiftly given and I felt well supported and the speed was fine - back in time for tea, as my partner used to say - and I felt much more in control than I'd ever imagined, even when it hurt before the epidural.
But she wouldn't have it. So bossy and annoying. I had quite a big tear (though no, I wasn't traumatised by it!) and I sometimes think was sewn up (painlessly...!) quite tight - and I'm quite small anyway.
Have ordered a "comfort probe". They're doing very well out of me!
