I can't help Myself...

As pathetic as it is now...me just attemtping to explain myself. I wasn't always like this, in fact I never could imagine becoming this type of women.
I grew up a good Catholic girl. I am for the most part a pragmatic person. I understand consequences and for the most part basic psychology and economics of ones decisions. But I am stumped at my current set of circumstsnces...
I am constantly thinking about sex. I can literally not stop craving it from all sorts of people and various times.
I saved myself for the man I am currently engaged to. First kiss first everything. And it wasn't difficult I never felt torn or regretful. I tend to lack efficient manners of affection and to this day actively work on being sweeter and more intimate with my fiance. We have been together for 5 years and he is the one. He is all I want for the rest of my life but sexually I just want much much more.
Are sex is great and never an issue but as soon as we finish I want more. I want to lock the doors and shut out the world and just play and play and play together.
Well that sort of fantasy is not achievable. We have a life we have careers and also I'm sure even after weeks or months I wouldn't want to stop. This craving is an abyss inside me and I am not entierly sure why this is happening. I've been dealing with it for most of the early year...but this desire has begun manifesting into unhealthy behaviors.
I've started suddenly dressing more erotic or revealing. I've always been more comfortable in modest and respectful clothing, however, have purchased many tight fitting and revealing ensambles. And this of course, hasn't gone unnoticed from others around me causing men to make advances or offers in which I am actually tempted. I have not partaken in any offer, however, I've come close enough that I revealed this issue with my significant other and have been enrolled in a behavioral therapy. The first therapist was great until he cancelled my sessions due to "unprofessinal circumstances" on his part. I never caught eind of his xhalenge with me so I was frustrated for awhile starting with a nee therapist. I was recommended a female and she is ok but she tends to want to link my fantastic childhood to this behavior and her Freudian references are starting to become redundant and unhelpful. So in total helplessness I'd like some advice or personal anecdotes to assist me on this journey. I don't feel trapped with my spouse in fact since I've met him it's been nothing but freedom and acceptance supporting my goals and dreams. This notion of behavior really began shortly after he proposed last year. I want him but I also want sex uncontrollably and constantly that it's began to affect my law studies, political projects and career. Please help before I lose all that matters most to me.
