While the kind of clothes you wear, cologne you splash on, and dating atmosphere are all essential factors that influence the success or failure of a first date, what you say will also serve as a worthiness indicator for a second rendezvous.

Below, you will find a few topics that are better left unsaid for a first encounter:

Topic #1: Your Past Relationships

When talking about past relationships (unless she inquires), it usually ends as a lose-lose situation. Many people tend to mention too much about their past lovers on a first date.

If you talk badly about your ex-girlfriend, it often appears as if you haven't gotten over her yet.

If you talk too nicely about your ex, it still sounds as if you aren't over the relationship, causing your date to question competition and relationship security in the future.

Topic #2: Her Past Relationships

Guys generally think they are delivering a compliment, but one of the worst things to say to a woman on a first date is, "What is a good-looking gal like you doing single?" Most cases, the preference is mostly not by choice.

Do you really want to know that her ex-boyfriend slept with her best friend or that she hasn't met the right one?

To avoid an awkward turn in conversation, let this type of information naturally flow from her lips. You never know when you might reopen a wound from her past.

Topic #3: Complimenting Other Females

While this topic of conversation is thought an obvious one to avoid, there are many men who slip at the tongue and speak to their date like they would to their buddies.

When an appealing woman walks by or a set of attractive curves has caught your eye, it is unwise to share these observations with your date.

If your wandering eyes haven't said enough, it is best you don't exclaim something inappropriate such as, "Do you like that dress?" or "Would you ever wear something like that?"
