Best New Years Ever ended with more bang for my Buck....but was the currency all wrong?

Sounds like you had a lot of fun. Don't worry. Don't say anything until they do and don't volunteer any information. AND don't apologize or get nervous when someone grills you on what to they saw or heard. Standup to it, admit it and in the mean time get an std test. If he wants to see you again, go for it but don't be ashmed if spotted by friends.
