[M4F] Trying to understand my breeding kink

I cant help myself think about breeding, the raw passion, the intimacy and something deep inside me telling me how perfect it is. I have had a breeding kink since my early twenties, it started as a thought that creampies were hot but developed into a full blown kink. My ex hated it, thought it was disgusting and degrading to woman. I refused to pressuer her into something that made her uncomfortable. So for many years I never brought it up, never pressured her and tried repressing the urges. I think this has only made it worse, more intense. To the point that i am worried it is more an obsession than a kink. It feels so natural to me, like my cock was only made for this. Some passion and intimacy will always be lacking without it. I dont understand why it drives me so much and why it seems to control every aspects on my fantasies some days. I need help to understand it, I want to know if anyone else feels the same way and is as driven by it as me. If not it might just make me feel a bit more normal.
