Ladies, what does it mean? Comments please...

So a good friend of my wife, very hot body always bends over around me showing her thong or ass crack if she's not wearing thong or panties...
Is she doing on purpose???
the other day her and her husband had people over, I had to leave early and she gave me an "extended" hug pressing tight up against me...
What is she up to?

Or how about this one, a female friend of mine and I were out one night, we were talking about sex and sex clubs and had a few too many drinks, so I showed her my xhamster profile.
Should I have?
