If marrying in two months, should I start masturbation?

Not related. Don't know if you are male or female. Don't understand the significance of question and marriage or no marriage. If you are not or have never masturbated, there is nothing compelling you to do so now. In consumating the marriage, you will have sex and hopefully orgasm (male and female). It would seem masturbation could be counterproductive in this situation. Otherwise no effect if you do.
No reason. Have a wonderful wedding and hope both of you live happily ever after.
