My ex's boobs makes me hallucinate

Long story short, after series of club/bar hoppin I had my first real gf for 6 months. When we broke up the feelin was no other cuz I be droolin all over her, from pictures to old videos. Its just the tits, I feel like its talkin to me. The break up was 2 years ago, I've groped different shapes and sizes but I still love em babies and im dying to see em again,. Is it normal? I mean just talkin bout it makes my penis alive, and she might be only slightly larger than A cup. Is it normal or am I psycho?
