There will always be an inherent Bf ex sex with an ex because of the shared history and familiarity. My ex and I mastered the first, but when it came to the hard, real-life topics? He always had one foot out of the door and no matter how much I reached for it, I could never get a firm grasp on his heart. My ex and I never had a problem in the Bf ex sex. And that love is much better than sex. Or … a dozen.
