How long does vaginal fluid survive outside the human body? (stripper fluid)?

I know this been asked several time but in specific I like to refer to an encounter I had at my buddys bachelor party a month ago, basically I was bought a lap dance, when the stripper got on my lap she asked me what was in my pocket I told her my cell phone, she asked me to take it off, here's the part so I took it off, she then took my phone and put it on top of her panties... Here's my question... knowing what they do with their hands, she may have touched many places with her hands which then touched my phone, also the fact that my phone was on top of her panties worries me that if she had any discharged or anything it will then stick on my phone... I have since left my phone in my pocket and left it there for 3 weeks, recently I took it out and wrapped it in a shirt... I am wondering if the stripper indeed does have any form of std can that virus still live on my phone as I have not used my phone for a month... Any input is welcome and appreciated.
