Girls kiss Girls

I like to kiss girls sometimes so what? I never looked at is as anything unusual. But people who hear that think it is weird and tell me that I'm lesbian or bi-curious. The more I think about it I don't know if I could seriously go any further than just making out with a girl. The question that's been stirring up in my head is could I be in a relationship with one? This came about within the last few days after me hanging out with my best friend who is in fact a lesbian. There is no doubt in my mind that I love this girl. We tell each other everything. We know and accept each others sides bad or good. We understand each other. And sometimes we even think alike. Sometimes she would hit on me and when we drink together we always end up making out but I never would let it get passed that because I was scared it would ruin our friendship. She is my best friend but could she be my girlfriend? We always joke about dating each other but today I was actually considering it.  She told me she had a crush on me since high school and that she wants to try to date me before I leave the state. Being as open minded as I am I want to try everything at least once in life and so far I've never tried dating a girl. And what's a better way than trying it with your best friend who already understands and loves you? We'll see...
