If you are a guy who has a lot of different casual relationships at one time or very close together, then you are not doing yourself any favors. Sure you may be having fun with women on your terms, but there is a difference between just wanting to have fun with women who want the same thing, and using women that want something more. Using women that are not expecting just sex or a few dates is called be a womanizer, and it will get your nowhere in life.

First, after breaking so many hearts you will become accustomed to women reacting to you in a bad way. That is not normal! It will become part of your routine to be looked at with resentment and anger and you will take all of that in emotionally, which will have an effect on your health. No one likes to be the bad guy and looked at with anger.

Plus the word about you will get spread around very quickly between all the women who know each other. The chances of you picking up another woman at the same place you did before will be slim, and women will start to look at you as a jerk before they even get to know you.

Secondly, adopting that kind of behavior may leak over into other parts of your life. Once you start to be aloof to women's feelings and looking past the way you treat people, you may start to treat other people without respect as well.

Your family, co-workers, and even strangers will not appreciate this kind of behavior and it will influence the way people look at you. You could lose relationships with them because of this. You can also suffer at work if your peers see you as an irresponsible guy.

Thirdly, you are at risk for STD's and you are capable of giving them to these women. Chances are you are not getting tested for sexually transmitted diseases between the women you are sleeping with, which is scary and irresponsible. You can easily pick up a disease and not know it, which puts your life at risk. And you can easily ruin someone else's life because of your womanizing ways.

Lastly, getting a girl pregnant is a huge possibility for guys who are playing the field. Just look around and you will see that's true. The more women you sleep with the more chances of pregnancy, even with the use of a condom. You are setting yourself up for the very thing you are trying to avoid - lifelong commitment to someone. Not only will you have to be in the child's life, but you will always have to have some sort of relationship with a woman who you mistreated and possibly hates you.
