Well....if it feels good and has health benefits what could be wrong with it?
if you can complete the act along with learning something, then you are on the right track. You, may also keep this to yourself.
It's not wrong at all for anyone in general to do that. The genitals do contain muscles and muscles do need to be "exercised" in order to stay healthy. Just remember, however, exercising too much can be bad for your health.
