Am i weird?

Hello my name is Luke I'm 23 and im in a happy relationship.I'm writing to seek some advice or closure I guess, for a while (ever since I discovered I was Bi-sexual) I have been turn on by the idea of being dominated.Not the BDSM kind but more like the ummmmm 'forced sex' kind.Now I've played these fantasies over in my head lots of times but I've never been able to tell my boyfriend.I know it's weird but what do I do? I want to share this with him but.....I'm afraid I will drive him away.P.S. we are in a LDR just for those who might suggest that I suggest it as Role-playing ideas.
