Regular MNer and have name changed in anticipation of this thread - I'm sharing in case this might be helpful for someone or if someone has a similar experience and can reassure me.
Had first and last DC 4.5 years ago. Very traumatic birth for both of us, long, long labour, episiotemy (sp?), forceps. I was very, very battered and bruised down below but healed well eventually.
After a few months when everything had settled down I noticed that I had much more vaginal discharge than before. I constantly felt wet and damp and my pants were a mess (I did warn you about the TMI). I felt that I got a bit "stale" smelling just a few hours after having a shower and became really self-conscious. 
Well, you know how it is with a new baby and everything else. Going to the doctors was way down the list of priorities and after IVF, pregnancy and birth I was not keen on having even more fiddling down below. But I eventually went a year ago and the very nice doctor checked me over, said there was nothing obviously wrong but that I had some very large skin tags on my fanjo wall which might be the cause of the increased discharge. She gave me antibiotics in case I had an infection but I was no better.
I eventually dragged myself back and got a referral to a Gynae consultant - my appointment is on Wednesday afternoon.
Apparently I might be able to choose to get my extra fanjo flaps cauterised off 
but will find out more on Wednesday.
So, that's all. I'll let you know how the appointment went if anyone's interested (have already booked into nice restaurant for meal with DH following appt in case it is traumatic)
