Hi Iggysgirl.. welcome

Only time is goning to make you realize that your ex's opinions aren't worth your time... that his opinion is not important and his close minded inability to grow with you is something that he will no doubt come to regret.

Share your concerns and your thoughts with your bf. Odds are, he is more accepting of your sexuality and most likely is thanking his lucky stars that he has found such a sexually adventorus woman to share his life.... communication is the key... be honest and open about your thoughts, desires, and no doubt he will be very interested in sharing all of his with you...

Good Luck.. and welcome
