That's your cervix, the "neck" that opens into your womb. It's not your actual vagina getting aroused, it's your cervix opening to (presumably) allow little spermies to enter. It can be mildly uncomfortable--the opening sensation is very closely related to the way your cervix opens to allow the release of menstrual fluid (ie, cramps) or dilation if you were having a baby (that's what labor pains are).
