More About Period Play
Some women will not engage in sexual activity while having their period although some do. It is perfectly safe to engage in all types of sexual activity during menstruation provided that the partners are fluid bonded or do not have a transmittable disease. Some individuals will limit period play to fingering, or simply exclude oral sex during menstruation. Some might only engage in sexual activity in the shower during that time.
