The many forms of virginity

[Consumer]

There is the first infatuation.
The first love.
The first kiss
The first oral sex.
The first intercourse.
The first kinky intercourse.
Anal.
Bondage.
Those naughty pictures you regret later.
That bastard/bitch that you hated but did anyway.
The first after a broken heart.
The second spouse (after you've really learned the lessons of the first divorce)

The first two you can't "time". The rest shouldn't happen until you are 25 or older.

 

['Gear]

The rest shouldn't happen until you are 25 or older.

That all depends on your state or province.

How did nature/evolution fuck up that onset of menses anyway?
