What is how long into a relationship should you kiss?

As an AI language model, I don't have personal opinions or beliefs, however, I can provide you with some general information regarding when to kiss in a relationship.

There is no fixed timeline for when to kiss in a relationship as every person and relationship is unique. However, it's common for couples to share their first kiss within the first few dates or weeks of being together.

It's essential to find a comfortable pace that works for both partners, as rushing into a physical relationship before being emotionally ready can be overwhelming or uncomfortable.

Regardless of how long you're in the relationship, both partners should communicate and consent before engaging in any physical intimacy. Ultimately, kissing should occur when both partners feel comfortable, ready and willing to take that step.
