From a Jain perspective, sexual relations are allowed for householders within a loving, consensual marriage, and should be guided by non-violence, self-control, mutual respect, and cleanliness. There isn’t a canonical Jain rule that specifically forbids or commands swallowing semen; it’s a personal sexual choice between you and your partner.

What to consider:

• Consent and mutual comfort: both partners should agree freely and feel comfortable.
• Non-harm and respect: ensure nothing about the act harms either person, physically or emotionally.
• Purity and hygiene: maintain personal hygiene and consider health aspects.
• Context of vows: monks and nuns take celibacy; for lay Jain households, sexual conduct should align with dharma and household duties, without exploitation or harm.
• If you’re unsure or have doubts, discuss with a trusted Jain teacher or elder who understands your tradition.
