Will the practice of superficial masturbation affect marriage in the future, and will practicing it during menstruation cause infertility?

Masturbation is forbidden and has many harms. One must repent sincerely and not return to it. It is not necessarily true that it will affect marriage in the future, but one should beware of the ill-omen of sin, for a servant may be deprived of blessings because of it, as Allah Almighty said: "And whatever strikes you of disaster - it is because of what your hands have earned, and He pardons much." As for it being a cause of infertility, specialized doctors should be asked about that. There are specific guidelines for getting rid of this habit that can be reviewed.
