I have this problem since elemantary school.I was really fat so not many girls really talked to me and I grew up without father so I had no one to have as a role model. You know that classic I am so ugly,stupid and not even worth to have any girlfriend. So I told myself I loose fat,have good body everything is gonna be amazing and I am gonna get so many girls. So after 4 years I finnaly have somewhat good looking body,managed to get some girls but I still cant seem to understand how this dating and picking ups girls works :D I just thought that if I look good everything is gonna go by its self and I am gonna be on easy mode.Well long story short hell no.I watched a lot of Youtube videos and everywhere you see : "Just be Alpha male","Be that best guy in the room".But how the hell do you do that :D Almost every girl I have been with tells me that I look like the type that just wants to fuck them or type of guy that changes girlfriends every week.And none of these "relationship" lasted longer than 2 months.I have no idea what I am doing wrong :D
