So I recently started dating a girl who is 2 years younger than I am. Before now she had told me that she had been with about 5 guys previously before we started dating however before I asked her out she said that she was late on her period. I helped her through it and this past Monday or Tuesday ( can't remember) she got her period. A day later she told me that she thought she needed the morning after pill because some guy tried to pull down her pants and somehow masturbated on or near her vagina. I was very suspicious of this because why would a guy want to have sex with a girl who is on her period number 1 and number 2 she told me that he said "i thought you wanted this" so this leads me to believe she led him on. The next day after a brief fight she was over at my house for about 5 hours and did not go to the bathroom once (I assumed she would to change a tampon or something... ) and then last night I was at her house and proceeded to finger her... no blood.
Here are my questions
1) is it possible she was lying about her period completely? I know that they can last 2-3 days sometimes but damn that was like lightning.
2) if she is lying is it to get attention from me?
3) is there a possibility that she's just a virgin?
I'm sorry this post is so sporadic I've been thinking about it for a while now and I needed to ask for advice.
