Should I let my bi friend suck me again.

So long story short, I have a bi friend who invited me over to play games. He played me and I watched porn with him so I got hard and needed to get off. He sucked me off and I liked it but after I came I was disgusted. I backed away without telling him and washed off in the restroom. I don’t like guys or anything but in the heat of the moment I let him suck me. Thinking about it makes me uncomfortable but when I get turned on again I want to do it so bad. He invited me again but this time he said he wanted me to spend the night. I asked why and he mentioned wanting to try it under the sheets, in the shower, and on his kitchen counter with him bent over. He wants anal already and i’m so confused!? What decision should I make!?
