Im sexually frustrated.someone plz help

So...this might sound weird but I dont know what to say or do. This started in May, I had a dream that my sister's boyfriend was standing in front of me naled in a dream. I thought ok but didn't pay attention to it. Then I've had countless dreams sexually with him. I had one where I almost suck his dick. Also one where we he was about to stuck his dick into me. Now im not gay but now I look at him and I want to know what he is packing cuseknow what they say about black people lol...and to see if he's good in bed. I know it sounds gross but idk what to do or say or anything. Here is a picture of him. And give advice plz and thank you. And I wouldn't mind having sex with him but I don't consider myself gay.

What you said IS gay. It's ok to be gay. Also it's possible to be bi. Talk to your sis. Ask her f she can help. DO NOT BRING UP HER BOYFRIEND.
