i have had a similar issue too and like traveller it was mostly thrush. my gp recommended a 2 week course of canesten pessaries (which the chemist wouldnt give me so i had to argue with them). i was also diagnosed with vagimisus (sp?) which occured because of the thrush and had to see a counsellor about it. you really should see a gp. is there a nice female one around? i found females more comfortable then males. they are much gentler and easier to talk to about it all. plus they can sometimes relate to what you are going thru. we now use plenty of lube when DTD and other stuff so that its more pleasant for me. plus i have gone from being able to DTD once or twice a week to now able to do it anytime without any pain at all!! good luck and let us know how u go.
