Is it rude to ask personal questions?

Question

Example:At what age did you lost your virginity?

What would you think about me if I ask you this question?

Answer 1

If you asked me that, I'm surely think you are really rude and not that even a pervert. I just hate asking questions about my privacy. But still depends on the person.

Answer 2

no not really, depends, i like those questions

Answer 3

I would think you were being intrusive. If we were in a relationship that would be different but if you were just a friend or stranger then I would think it rude.  

Answer 4

It depends who you're asking, if you're asking me, yes it's rude because I don't know you. If you're asking one of your friends then I don't think it's rude. Something like viriginity is personal, meaning only if someone feels they need to tell you they shouldn't or don't have to.

Answer 5

I would think you were rude.  Some other people are more than happy to spill that sort of information though from the "I lost it at 13 and regretted it" to the "I lost it at 16 to this guy I never have seen since I graduated high school, but it was the right thing to do."  It depends on the person.

Answer 6

No that's not rude to me, it's no big deal.

Answer 7

yes, it's rude to ask personal question even more when you don't know very well that person.

I don't like people asking me such kind of questions.
