If the feelings are pure, conscious and true nothing is wrong1
While it is perfectly normal to think about kissing in the moments before the meeting. If you're having a good date, the conversation is flowing and you can feel the sparks flying between the two of you, why not….
See if you have chemistry
While you may have a lot in common, kissing on a first date lets you see if you have any romantic, non-platonic potential. If the kiss is as great as the date, that can be a great indicator that you have matching styles.
Enjoy the moment
Another reason people like to kiss on a first date is that kissing is—let's face it—fun. When you have had a nice, attractive and exciting first date with someone, ending the evening with a wonderful French kiss can be a way to add an exclamation mark to the wonderful time you spent with each other.
Leave the next meeting
Those who are against kissing on the first date often believe in the "less is more" mentality. While you've clearly had a great time with this person, there's something about leaving them wanting more that can work in your favor. By turning down a kiss on a first date, you become more motivated and inclined to go on a second date.
Trust your gut
When it comes to kissing on a first date, it's important to understand that it's entirely your decision. Since no two first dates are alike, it's up to you to decide if you want to kiss this person or not. There are many factors that can play a role in this decision, and sometimes the location of the first date, the time of day, or even the weather can be the reason to kiss or not to kiss at the end of the date. The key is to trust your 'gut' and go with what your instincts tell you.
