Re: Can a doctor tell if you are a virgin or not?
Again agreed with Blastoff.
Unless it was extremely recent (as in that day) then there's really just no way to tell 100%.
And even things that you find when doing soemthing like a rape kit evaluation (such as tears or irritation) can be attributed to other things as well. None of it is a 100% definite sex sign.
In conclusion: there is no way to tell 100% by physical examination that you have had sex. The only way to tell 100% is to ask someone during a polygraph test...or if you catch them in the act!
