Past Lives?

I have been regressed to past lives by myself and others many times.  I'm not sure why, but I don't think I've learned my lesson yet!  In the previous lives I have visited I have yet to see myself as the opposite sex. I'm sure there are plenty I haven't seen, but the ones that have been presented to me are obviously the important ones relating to my present being.  I was always alone.  I'm thinking it's because I've not walked in the shoes of the opposite sex, so I don't understand their side of the story.  Hopefully the next time (not that I want a next time) I'll get to see the other side of the story and learn that love in our life IS THE SPIRITUAL JOURNEY!
