Answer

In Jain Dharma, swallowing semen/cum would generally be considered not appropriate for a Jain seeking to follow purity, self-restraint, and brahmacharya.

Explanation

Jain ethics place strong emphasis on:

• Brahmacharya — celibacy or sexual restraint, depending on whether one is a monk/nun or householder.
• Indriya-sanyam — control over the senses.
• Shuddhi — purity in conduct, thoughts, and habits.
• Ahimsa — avoiding harm as much as possible.

For Jain monks and nuns, any sexual activity is completely forbidden.

For Jain householders, sexual conduct is expected to be restrained, responsible, and within moral boundaries. Acts driven mainly by sensual indulgence are discouraged because they strengthen attachment, passion, and karmic bondage.

Spiritual Understanding

Jain Dharma teaches that liberation comes through reducing passions such as lust, attachment, and craving. Sexual indulgence increases bodily attachment and disturbs inner purity and self-control.

Takeaway

From a Jain spiritual perspective, swallowing cum is not encouraged. A sincere Jain should aim for restraint, purity, and gradual control over sensual desires.
