some people will tell the truth, some will lie, you may not even know after you really get to know the person.
well, some timing might be good. don't ask right after ... were you a virgin? that poor guy might not be and might think that he did so bad that you think he's a virgin. hehe ...
not always true. do you know masterbation? know what i mean? i know some guys in here know what i mean.
There's no physical tell-tale signs that a guy is a virgin or not, unlike girls who will usually bleed during their first time. But most likely you can tell when you are doing it with the guy. Inexperience.
actually most guys would admit if you ask them. As long as your not asking them to make fun of them then usually no harm done. But i agree, there are some people out there who say they are virgins but aren't.
well my first time i had sex for 5 hours so thats not true and i told her i wasn't even tho i was.lol as of now i cum fast, but thats by myself i always seem to cum faster when i do it myself.lol so theres no real way to know.
