Nickyp, VA for me has been at times intensely sore & like Sparkle's comment, just inside has been one of the worst areas. In fact, I've recently been advised to double up on Vagifem, using 2 tablets three times a week, 1 inserted high up & one low down to try to improve the area just inside.
There have been times when I've thought the VA was under reasonable control & felt relaxed about sex, only to find that on penetration, despite using a good lubricant, it's felt as though an unsuspected sore area has been torn open. At other times the whole vaginal/bladder area can feel persistently inflamed for no apparent reason, so that it's impossible to know whether the discomfort is due to a UTI, thrush, something else or whether down to VA alone. With VA the tissues of the GU tract (ie bladder as well as vaginal area, inside & out) become thinner & so much less robust & this, together with the decrease in natural lubrication that in fertile years helps balance the flora, means it's easier for infection to take hold.
Please don't be afraid to ask questions here - nothing is silly, taboo or tmi! We are all learning from each other & like to help if we can.
