How Can I Relax & Embrace Pleasure During Pregnancy?

Dear Betty,
first of all, thank you for doing this noble work of yours.
I have been in a loving, monogamous relationship with my man for about five years. Before him, I had six partners and not really fulfilling romantic or sexual life. My first partner was satisfying me, but I cannot even remember the details since it was very long time ago and I mostly remember being very unhappy about him not wanting to be anything else but my fuck-friend.
