Im obsessed with creampies

Im a very very horny person I'm 22. But ive always been this way. Shortly after losing my virginity i started a relationship with a girl. One time i accidently cummed in her and we both found out it turned us both on. I from that point on became addicted to this feeling. But ive had enough self control to not do it, obviously because i have no children. I'm just wondering if thats normal and do girls like it when i guy does cums in them. Does it turn them on as much as it did me and my ex.
