Odd question about testosterone after a workout.?

I have been doing research and some studies say that testosterone levels increase 100% within ten minutes of watching pornography. *If you were to work out, then right after the workout maintain sexual arousal, would this help increase the muscle built?* I thought the reason why steroids worked is because they increased testosterone which helps build muscles. Or perhaps I'm trying to find a healthy steroid. Please explain why or why this wouldn't work. Maybe the research is flawed but I might as well ask. Please answer the question in the asterisks.
