a good question, let me break it down:>Jonathan
Would never, not because he doesn't care for Speedwagon but because he is betroth to Erina and couldn't break his promise of monogomy.>Joseph
very likely, and would probably turn it into a competition of sorts.>Jotaro
likely. Jotaro seems almost asexual despite having a daughter. He'd probably do it since the Lovers fight showed he's willing to embarrass himself to save those close to him, but it wouldn't be romantic or nice. It would be fast and hard, and he'd try to end it as soon as possible.>Josuke
Not likely, though possible. Josuke seems more like a typical teenager than Jotaro and would be pretty self conscious about fucking a guy, He probably catches a lot of shit for his feminine appearance so I bet he's fairly insecure. Still, he and Okuyasu get along really well and I could see them hooking up under the right circumstances. Josuke's curious enough that he could use a stand attack as an excuse to explore that part of himself.>Giorno
Absolutely, since any ally is crucial to attaining his dream. He wouldn't even think twice about it.>Jolyne
She's probably chomping at the bit to get some of that sweet sweet brown sugar>Johnny
Probably. Johnny and Gyro both seem pretty experienced and comfortable with their sexuality so I bet they'd be up for it under friendlier circumstances. If anything, the stand attack would be a deterrence since neither would accept being forced into something.
