Is she in denial?

I need some advice\help,I been dating this girl for 7 months and we are really in love with eachother our chemistry is crazy I mean it's like sum crazy shit where we get mad at eachother and than chase eachother all over the city just to make up and make love all over again. Situation is I'm the first female she been with.When we first meet our vibe was cool she said she felt comfortable around me.Anyway we started talking on the phone than started going out original I thought she was curious because she was asking alot of questions about the lifestyle and was very friendly towards me in a flirting way.When I ask her she said she wasn't bi curious or gay,so this is the thing she says she only attracted to me and no other females she say it's just something about me. I am a masculine female a stud so I can see her being attracted to me in that way but her telling me she don't consider herself lesbian or bi is bugging me cause she consider us a couple plus her friends know about us but not her moms.I guess my thing is she don't consider herself in the life she say I'm the only female she will only date and she admitted to one day she will eventual want a boyfriend again but don't want to lose me...Please tell me what I should do or what you think is goin on wit her denial.
