Is it normal since coming out i have only dated black men?

I have had a attraction towards black men my entire life. But i hadnt known how serious it was until college. I had met this one guy who i ended up having a deep conversation with and we both were curious and super attracted to the other we ended up having sex. We sort of snuck around for a month which in my opinion was really hot. But we stayed close. The part i leave out is that the sex was so mind blowing and i think adds to the lust part. But as time went on he came out to his peers and didnt force me but told me i should come out too. I did. We dated for another six months then it ended. I had gone another 3 months alone not speaking to anyone when his friends hmu. There were 2 of them and they were pretty casual at first and invited me over to drink. After some conversation and halfway through the bottle i gave into my loneliness and horniess more and had a threesome with them and got spit roasted. (Another fantasy)
I feel so guilty about it and powerless to stop my urges. But i am weak to BBC.
