Like a Virgin

You're right, it's none of their business and you should politely tell them it's none of their business.  

I'm wondering why you wouldn't care that they ask if you weren't a virgin.  Whether you're sexually active or not with someone you're dating is between the two of you, no one else. 

I had sex long before I was married and that wasn't anyone's business either.  When people would ask if we were having sex or make sexual comments, I would tell them what he and I do is between him and I, no one else.   

Oooh, your office sounds like mine LOL

Seriously though, I've found that the more about us we share, the more people will comment. The office staff who are open about what they do get a lot of joking and questions. However, those who keep their personal lives to themselves seem to miss out on those conversations.

I'd say if you're not comfortable with them joking, then try to avoid discussing your personal life.

They seem to be wanting to feed of your juicy news....depending on how close you are too them and how you want to be perceived....I'd be inclined to actually play or joke along with their antics.....give them something juicy to feed off..... like for instance... "he was OMG".....

They will probably lose interest if they think you've done the deed and stop asking....
