Super low sex drive & inability to orgasm...?

Has anyone else experienced this problem? I switched to Skyla IUD after being on the pill for 8 years in hopes of regaining pleasure from sex. I'm in a loving, long term relationship and this is our only issue. I also take Wellbutrin for anxiety, which I have heard can damage your libido as well. All I want is a mutually satisfying sex life with the man I wish to marry. Any advice? I can't be the only woman going through this! Thanks in advance ladies :)
