Short answer: Jainism does not endorse or promote the idea of consuming semen. The tradition teaches self-control over sexual desires and that sexual relations are appropriate for a married layperson, while ascetics practice complete celibacy. Any act that inflates attachment or harms spiritual progress is discouraged.

Key points in Jain teaching:

• For householders, sexual relations are allowed only within marriage and should be moderate and faithful; excessive indulgence is discouraged. Celibacy outside of marriage is vows-for laypeople as part of brahmacharya. ( jainknowledge.com)
• For monks and nuns, complete celibacy is mandatory. Thoughts, speech, and acts related to sex are avoided as part of the path to liberation. ( bbc.com)
• The core aim is reducing attachment and karma by controlling sensuous desires; masturbation or lustful acts are considered violations of restraint in many Jain sources. ( jainqq.org)
