I would be unsure about being with someone who wants to get you into her bed right away without a condom. STDs and HIV can still spread even if she takes the pill. Why would a friend introduce you to a girl like this? My guess is not about starting a relationship, but simply to have meaningless sex. She also wanted to kiss just to kiss, there was nothing behind it, no reason, it doesn't make it special

Do not be regretful for taking precautions, better safe than sorry
