A ball press may be used during cock and ball torture, a practice where a submissive male receives pain to the genitals. This practice is a useful way to punish a submissive or reinforce the dominant and submissive roles within a BDSM relationship.
A ball press can be used on its own or in conjunction with other BDSM practices, such as bondage. This further inhibits his movements, making him feel even more vulnerable. The dominant could also increase the sensations the submissive feels by inserting an anal plug into his anus.
