Sounded like a cracking night out and I think that you may be a little paranoid, is anything wrong with you yet?.
Strippers are not necessaryly prostitues and I do hear that a lot of women earn a lot of money from stripping rather than working the normal nine to five.
Lets face it ,because was a stripper is irrelevant,it could be anybody unknown who you could have done it to.
Personally the chances are low (if at any) that any sexual transmitted disease could be passed by a twister.
You are more likely to become ill eating from that dodgy burger hut outside.
Forget about it until something is not right or you will become paranoid about every little thing.
