Well, here are the pros and cons. Your hand (whichever you prefer) wouldn't get pregnant and you're hand cannot deny anything that you say so you can do whatever with it and whenever. However you may feel bored with your hand and might move on to something that has more "feel" to it, so you seek a woman or a man, for sexual pleasures. Though she or he may give you a good time, it may also backfire on you, for one women tend to get pregnant and two you will be classified as being a homosexual for having sex with a man as well as increasing your chances of having STDs. Overall, your hand may be fun at times, but the thought of you doing that to yourself may bring shame and dissatisfaction towards yourself or the people around you. Your "partner" will give you a good time or it will just screw you over. You call.
