i think a lot of people have the same problem you do. i can be doing cardio and all of a sudden i get an erection! and i have to stop. i get erections in the locker room, shower, grocery store, gas station, etc. it's just natural! some of us just have more hormones flowing than other guys. i wouldn't recommend jacking off before the gym though, i find that i have less strength. what is better than having a hard sweaty workout to get the testosterone flowing and then masturbating in the shower? don't worry about it!!
