If someone were to see a pretty girl kissing another pretty girl, they would think Lesbian.
But why even worrying about labeling it.
As the line from the keynote song in the movie Casablanca says:
"You must remember this
A kiss is just a kiss, a sigh is just a sigh
The fundamental things apply"
If you close your eyes when you kiss, lips are just lips. Just hope that the lips are soft.
