What are the legitimate ways for an unmarried young man to check on his sexual health, given that he rarely experiences wet dreams, and is masturbation considered one of these ways?

It has been previously stated that masturbation is forbidden and is only permissible out of necessity. The mere desire to reassure oneself about sexual health does not permit masturbation, as there is no necessity in that, nor is there any relationship between its infrequency or frequency and sexual health. Therefore, these intrusive thoughts should be abandoned. One can consult the counseling section of the website regarding sexual health.
