But also...
EUPHORIA.
The first time I can remember, was about age 13 visiting at my aunt's house in another city.
My aunt had big beautiful breasts, and I wanted to have those, too.
I slept many times in one of the bedrooms of her big house, where she had lots of spare female "goodies" such as extra bras.
I now confess, I tried them on many times.
I slept much or most of the nights wearing them.
I was scared to death she would wake up, and find me sleeping in her bras.
She was an early riser, at usually 5 am. So I always need to wake up very early, carefully take her bra off that I had been sleeping in, and try to fold it and put it back in the dresser drawer in a way that, I desperately hoped, she wouldn't notice.
Was I successful in my stealth? I never lied to hier, she never asked, so maybe she never knew.
Or maybe she DID know, but just said nothing.
Who knows?
To me, breasts are the ESSENCE of physical femininity.
It is really quite simple:
1) Girls have breasts.
2) Men don't have breasts (other than ugly MOOBS sometimes).
NOW I HAVE MY OWN BREASTS. My female boss at the University was staring at my breasts about 75% of the time she was talking to me this morning, for a good solid 3 minutes.
