I understand about the embarrassement - I think I would feel the same!

The idea of talking about it though... Is that the feelings arise from transference. The notion is that you project feelings on to your t that are feelings you have had for past figures in your life. Processing sexual feelings... Can help you feel less embarrased / ashamed about sex. Can help you have healthier sexual attachments / relationships in your present life... At least in theory when all goes well ;-)
