I think you should enjoy dating, more than stepping into a relationship if you feel this way...I'm always lookin and lusting after gurls every where I go...
Its all good that you like treating girls good, but the fact that you dump while dating just because you found someone better, you should consider is that person even worthwhile to be dating if their not good enough for you in the beginning to dump.
Your the type of guy I watch out for
...n-e-ways...I feel that you should really think about what you want and consider what the girl wants...you shouldn't hurt a girls feelings but you probably will if she's digging you and you give her a stupid reason to why you don't want to be together anymore.If you don't hurt others feelings, you probably have and don't know it by the info you gave.Just be open with the girls and let them know before hand what you want...she will respect that more than telling her that AFTER sleeping with her.
