Newly Single

Was in a relationship with a guy for nearly six years and for the last 6 months or so of the relationship I was just NOT sexually attracted to him. Like I had no sex drive at all and I never could figure out why... BUT now that I'm single I have been INCREDIBLY lonely and horny. And I have never been that way. It's really strange because I just thought I wasn't a sexual person or something but it's starting to seem like it was him... Anyone else have a similar experience???
