Is he really a virgin???

Question

I know they have scientific ways of knowing if a girl is a virgin or not but what are the scientific ways to tell if a guy is a virgin or not?
How can I tell scientifically if he is or not for myself, meaning I want it to be a fact....??

Answer 1

it's not scientifically possible... the only way you could tell would be through psychological profiling. You can usually figure it out just by talking to the guy or observing his interactions with females.
