I noticed in one ad that a girl said "switching hitting is her speciality".  call me dumb, but I don't know what switch hitting is.  can someone enlighten me?

She is bi-sexual.
She loves it all.
Normally means that she has a boubles partner.
Believe me, that can rock your world.
It did mine.

There is no such thing as a dumb question.
You are just new.
We all have to learn.
Have fun and play safe.
