People who have problems of sexual reluctance should go to a psychiatry. In some cases, not everyone wants sexuality. This is normal. However, being reluctant to have sex for a long time can be a serious problem. You have to go to the doctor.
Since sexual intercourse is done with two people, the other partner may need you too. Whoever is reluctant, a treatment method is applied on that person. The unconscious desire enhancer can also lead to potential problems. You should not use such drugs.
