In as much as we have things that turn on girls, certain things will turn most girls off. Girls can lose their attraction if they spot certain things that they don’t like.

Certain things that a guy does without knowing can be a great turn off. These actions may be involuntary or something that the guy feels is cool.
Below are certain things that girls do not find attractive.
Negative talks
Girls certainly get turned off by words that are not encouraging. Guys who are fond of uttering words that dampens the spirit of girls are a big turn off. Girls do not want any bad energy around them therefore they will choose to ignore such guys.
Rude boys
If you do not want to appear as a big turn-off to girls, try as much as possible to be nice and caring. If you are rude to others, girls will perceive you as an arrogant person.
Self centered guys
No girl would ever look the way of a selfish guy. Girls are attracted to guys who think about their needs. A guy who is selfish automatically appears to be self-centered and an incompatible life partner.
