I Recently Found Out I Have Gingivitis. It Isn't Because

I recently found out I have gingivitis. It isn't because of my my daily brushing they said it was more because I don't come in for cleanings like I should. 1st question. Can my partner get gingivitis? 2nd questions. I a. A lesbian so can my gingivitis effect her vagina? 3rd is I feel really awful about having it I haven't kissed her in about a week. Should I let it affect my life like this? Is it not that serious?
