L for ________?

i been wondering...
what makes a lesbian?
seriously.
i mean... sure i've had lesbian encounters.
its so much more common now, i'm sure a lot of females have.
but does that make me a lesbian?
or i dont know; bi?

a few months ago, i had a female friend who i knew was bisexual.
she came over to visit and she tried coming on to me,
but we eventually didnt do anything.
to be honest with you, i resisted her not because she was a girl,
but because of her other characters.

i mean; what makes a lesbian?
years and years ago, while i was trying to figure out what sexuality itself meant,
i had sexual encounters with some females.
They were about my age at the time, and we were young.
does that make us lesbians?

looking even farther into my memory
i remember being molested as a child.
i didnt think anything of it at the time,
but i knew it was disgusting not because we were both females,
but because i was too young to enjoy sex at the time.
the lady, was in her teens.
does that make her a lesbian?
did it make me one?

does checking other females out make me bisexual?
