That is so interesting. I've heard about that once before. I have absolutely no idea how that even works. I'm looking up information about it, but I'm terrified i'm going to accidentally get some kind of trigger. Well it seems legit. O_o Wow, like, what would that even be like... As far as I see though, only women get those.
Anyway, to actually answer your question - hahaha - you need to ask yourself. Does the behavior feel healthy to you. Remember, sex/porn addiction is very subjective. What one person may feel is healthy sexual behavior, another might find repulsive. Do you think your exercise-induced orgasm will disrupt your recovery? Do you think there is a chance it will make you act out more in other ways? Can you limit yourself to just that? I can't tell you what you should do with your body, only you can truly decided if you think a certain behavior is ok or not. Does your exercising in that way cause a trigger, or desire for you to go view porn? Or can you contain yourself? Just ask yourself these questions, and decide.
