Losing virginity: When?

I was wondering, and also other guys here, whendo you loose your virginity?
Wich act do you have to do to loose it? Is it penetration or is it oral or is it with hand...?
When can you definitely say that you lost your virginity?

I like women, so when I cum inside of them.

You lose your virginity when you have intercourse AKA sex involving penetration.

does oral count?

my 15th birthday.

I was 17 years old. My cherry got popped by a fellow waiter at work (married guy) in my car at the end of the evening shift. Loved it and haven't looked back.

Does virginity really exist? I mean I think the concept of virginity is overrated, especially for guys. I think a person loses their virginity when they become sexually aware, not during first penetration. So I believe that virginity in the physical sense is non-existant, but in a spiritual or "religious" way it might exist.

I was 16 the first time i had anal. I personally consider this the moment I lost my virginity. I had made out and had oral with guys beforehand, but i count "going all the way" as loosing it.

For guys you may be right

For females, they have that thing called a hymen...

I see what you're saying, but for the sake of the virgin appeal, people broaden their chances by excluding people who haven't had penetration sex. If you want a new car, your more likely to find one if your standard is "reasonably low amount of use" rather than "just came out the factory."

I think in the obvious, official sense, you lose your virginity when you have intercourse. But for me personally, if you go around sexually active and have anal sex, oral sex or give handjobs, you can't exactly call yourself a "virgin".

Lost my man cherry to a marine when I was 19 was great and then he let me fuck him for the first time...

I was thirteen the first time I had anal.
I was way to young, and was like asshole was child-like small.
It hurt so bad.
But yeah, I consider going "all the way" loosing your virginity.

I was 15 the first time I went all the way and had anal sex with a guy. At scout camp. God that was fun!
