I'm 6.2 foot and I don't 'slay' women.
I can't squat or bench shit. Dead lift isn't too bad.
I have tiny wrists and ankles and seem to be injury prone and even at a body weight of 230LB's and BF% of 13% didn't have biceps over 15.5 inches and calves over 16.5inches. Not every tall guy is destined built like waylander!
5.5 foot isn't that short, I would follow Arem's advice, if money is not an issue I'm a liberal and very expensive GP will gladly administer HCG to you. I know a guy about 5.5 who has slept with over 300 women! mostly hot to I know another 5.5 foot guy who has had a similar amount of pussy and has just married a smoking hot fate titted blonde beauty therapist.
If you are mainly concerned about girls my advice would be to make sure you succeed in business, work hard at college and do well in your chosen profession, women will choose a successful 5.5 all round decent guy over a 'broke as a joke' 6.2 foot all round decent guy any day.
Height is like looks-its not everything, I know a six foot guy who women literally throw themselves at, but he's a lazy mother fucker and doesn't work or have any ambition, and subsequently can't get a girlfriend. Women fuck him, chuck him and make a lame assed excuse whilst they go back to their boyfriends.
People who succeed are the ones who play the hand they've been dealt as best as they can and exploit their strengths whilst working at building up their weakness's.
