Yes, but be careful to control the frequency of masturbation and not to masturbate frequently for a long period of time. If you experience dizziness, headache, or weakness after the vaccination, it is best to avoid masturbation to avoid aggravating the symptoms of side effects. It is also important to note that if you masturbate just after the vaccination and you experience sweating all over your body, it may also cause infection at the injection site. It is recommended to keep the injection site dry and clean for 1 to 2 days after vaccination, so it is best not to masturbate. It is recommended to pay more attention to rest, stay up less, prohibit spicy and stimulating food and alcohol, and avoid strenuous exercise and heavy physical labor for one week after the new crown vaccine.
