Looks will surely get you girls and one nightstands but won't make you keep them. Familiarity breeds contempt. Overtime she will become desensetized by your looks. Therefore the type of a person you are will become more important than how you look. This is where confidence comes in. Its the same with guys, initially you are attracted how she looks, but overtime character become more important. Its the only thing that will captivate you in the long run. I know some people would say "She's not yours, its just your turn", but long term relationships are meaningful whether you break up with her or not. Short term relationships are not fullfilling. You can go to gym, Groom your facial hair and get a hairstyle, good hygiene but you gotta work on your game simultaneously. Get them with looks and captivate them with confidence.
