### Comment:
Can you explain the concept of consent in the context of sexual activities?

### REPLY:
Consent is when someone says "yes" to sexual activities. It is important to always ask for consent before engaging in any sexual act, whether it's kissing, touching, or intercourse. Without consent, any sexual activity is considered non-consensual and can be considered rape. It is essential to respect the boundaries and desires of others and to stop immediately if consent is withdrawn.
