Is it normal for my girlfriend to always place her vagina in my face?

So like I am a female. I am bisexual and have been in a relationship for three years. She is always horny and ready for sex. She is very possessive and gets jealous when I am around other females and/or males. She is extremely aggressive and into kinky sex. She loves foreplay and is awesome in bed. She does not care who is around, she will gladly fuck me in front of them. She has double d breasts. Every time she is around me, she puts her vagina directly in my face. So close that if I move 2in my lips will kiss it. I love her and all but is it normal for her to always want to give it up & place her vagina in my face?
