Of course women have standards. They would look like slvts otherwise and I highly doubt they want that.
As far as horny goes, they can be as horny as men under the right circumstances. Just last night this girl came over my house for no apparent reason. Then after a little escalation on my part, she was ready to go.
Here's the important part. She finally tells me that she has a bf, but that she's really horny and wanted me.
Nuff said.
