There are a lot of guys who think that if they show weakness or vulnerability they're not sexy anymore or attractive. In my opinion, you can't be too open or too gentle or kind or sensitive. If you really want to work on a relationship and have one that lasts, you have to be willing to go deep into human psychology and emotion. If you don't want to go there, you can be a serial dater, and I guess that's okay, but if you want a relationship with a woman, you have to be introspective and look at yourself and your family and where you've been and where you're going.
