Knowing when to go in for the kiss can be tricky. You want to kiss her, but you don't want to try to kiss her too soon, because that might scare her off. Considering she agreed to a second date, you can assume she is romantically interested in you.

Behavioral Cues

One tell-tale sign that a woman may be interested in a kiss is if she is playing with her mouth or licking her lips, says Elly Prior, a counselor and author of "Signs of Physical Attraction" on the Professional Counselling website. Another indicator of possible interest in a kiss is if she moves her head closer to you, possibly tilting her head. A woman who looks into your eyes and smiles is also likely showing a sign of interest.

Specific Circumstances

Consider the factors surrounding your second date that might influence her willingness to kiss you such as location and timing. Keep in mind that not everyone is comfortable with public displays of affection. While your date may have romantic feelings for you, she may not be open to kissing you in public due to her upbringing and personality, says TwoOfUs.org in the article, “PDA: How Much is Too Much?”

Cultural Factors

It’s also important to consider her cultural background, as that may also impact her willingness to kiss you on a second date. Gain insight based on her personality and opinions as to how her culture influences her, suggests TwoOfUs.org in the article, "Dealing With Cultural Differences in a Relationship."
