How to stop being too nice and add some sex appeal?

Recently, I have been told that I’m too nice and that’s one of the reasons I don’t really turn women on. I just don’t know how to change that. The way I am feels so hardwired and challenging to change. I need advice how to go against that and really up my “game” so to speak. I don’t want to be single for the rest of my life. From this post you can probably tell I am not really swimming in opportunities with women romantically. Help!!
