I am romantically straight but have submissive fetish so I want to have sex with various guys. My libido is the key and potential problem in context of penis and prostate orgasm

So long story short, I am not into guys but I am on the maximum level of submissive sexuality scale so I will experiment in order to make me feel vulnerable, controlled, objectified and exposed during foreplay and sexAfter just 24h without a orgasm I start to daydream about being in the place of girls in manhandling porn I watch. So that along compliments on my face and ass, along with hookup internet culture that's available... Why not?But you see my libido drives this. And after I cum, it's over like with girls(even though my refractory period is great) And I don't know a lot about gay sex. I want a great orgasm, but1)will I cum from my prostate being hit, (I think I am very tight btw)2)And if I do cum what about my ejaculation orgasm, 2)doesn't erection caused by foreplay or oral sex sometimes, or usually, go away when you start being fucked.3)What's in a "gay code" in one night stand context (or fwb) here? Will Top secure my orgasm after he cums? And how is that done?4)Will I want to have an erection after being fucked and if I cum or I will be too exhausted? How will I cum?5) Does libido go away after prostate sex is over or is a twofold libido?having great orgasm from being fucked but still being horny because I want to ejaculate actually seems like a perfect option, 6) but will Top (after he already came!!) want to go all over again getting me hard then making me cum?
