To prefer anal sex to vaginal sex

As a young boy my obsesión was a Womans boobs, the sight of a huge pair would give me an instant hard on, then something happened, a woman’s tots were important still but the ass was becoming more appealing, by the time I was in my midterms that’s all I could think about, and was constantly trying to get my girlfriend to let me do it to her, it did happen int my early 20s, and even then only a couple of times, the serous buttfucking started in my mid twenties and ever since then I’ve been obsessed with anal sex, I’ve broken up with very beautiful attractive women because they wouldn’t give yo their ass to me, I figured it was better to cut ties early before we invested any serious time in a relationship, any how I now tell them from the start that that is what I want, that and only that hole is the one I enjoy penetrating, sure I’ll eat Pusey and ass of course but actual fucking had to be butt fucking... is this normal??
