I haven't had girls stalk me, per se, however i've had plenty of women 'holler' at me, throw their numbers at me, and offer sex no strings attached. How did i do it? Since a very young age i have embraced my masculinity, partly due to culture and tradition, and partly through testing the field. In this 'game' the women chooses you, something most guys are oblivious about because they live on repressed memories rather then living consciously.
Living consciously and being aware of everything around you, like a predator, is the first thing i would suggest you do. This is how the sumarais in Japan mentally trained to make themselves fearless. This will be hard if you are not used to it, however practicing this will help develop the 'reptilian' part of the brain. The trick is to appear conscious of your surroundings while at the same time not paying any hot girl any attention. This will take much time to perfect, maybe a few years, however it is will worth it. Who doesn't want women chasing them? How do i know this works? well in highschool i would have groups of women surround my locker and would comment on how gorgeous and hot i was. Keep in mind however, this was not due to my 'looks', this is how these feminine females responded to a subconscious attraction they seemingly could not understand. There are many other examples, but i will not go any further, and keep in mind many of these females had 'boyfriends' LOL (note: this is why i am against 'relationships' because females will always be attracted to the alpha male due to acting on their 'emotions')
Second, to further develop your 'alpha' status, i would suggest you participate in competitive sports and activities which will seemingly also develop the reptilian brain. Activities like martial arts, weight training, hunting etc. are all very useful and helpful.
Always maintain power consciously and girls will respond. Read 48 laws of power and incorporate those laws into your life. for example, when girls throw their numbers at me, i still don't respond. Why, you ask? Because i am not the initiator (unnatural) and it would make me seem powerless. I must be the leader and the dominant figure in the relationship starting by initiating convo and leading every aspect of the relationship till i dump her ass. Never let girls disrespect you, even if it is in a joking manner. Remember, girls want to be fukced mentally and physically.
Contrary to what some guys (aka homos) like to believe you only must be average looking at best. I know many average looking guys ( I scout models so i am qualified to say they are average) who are doing absolutely amazing and they have nothing going for them except for having a very developed reptilian(aka alpha) brain. To start your conscious living as an alpha male, however, i would suggest you pay close attention to your BL, including the way you walk and talk at ALL times. Hard, you ask? Yes very, but will worth it when you perfect it. In the beginning you will have many people hating on you and saying how 'arrogant' you are but you cannot get discouraged.
To demonstrate how well this works in the field i will only say this. In college in the usa, people party to get laid, obviously, and most miserably fail at this. I, on the other hand, just walk through campus on party nights and women open me up and offer sex. It is that easy. Again, the hard work WILL pay off.
In summary, live consciously like an alpha, focus on your 'maleness', practice visualizing your unabashed sexuality on the opposite sex, and eliminate any female influences in your life. After a few years you will have so much pvssy you won't know what to do with it.
