Every PUA has his own approach that fits his goals to a tee.
Yeah, you're right. Every one has limits. I used to bang 3 different girls within 24 hours before I got into PUA. Don't get me wrong. This isn't 90 different girls in a month but 3 girls I banged every day for 6 months or so.
By the 6th month, I just can't take anymore pussy. I can't climb the staircase since my knees were shaking. I got so thin from all of the daily fucking. I felt so weak, I found it very difficult to work and my corporate career took a nosedive.
The girls knew I was banging each of one them and they all said, "May the best woman win." They tried to outdo each other on who's better at sex.
End result: My balls hurt like hell. I had to cut off the two other girls and retained just one-- the girl who helped me wash my clothes, cook meals for me, etc.
With that previous experience, my game plan as a PUA is to limit fucking to 2 days a week. This essentially gives me the opportunity to bang 4 different girls a week. No. I don't do quickies. I fuck for hours. Hence, I only work less than 20 hours a week at the current moment. I'm happier this way with lesser stress unlike in the past where I had to work 16 hour days as a corporate executive. (Yep, the guy who meets up with investors, joint venture partners, and other board of directors. I rose through the ranks from the lowest position.)
With that in mind, I friend zone every girl I sarge. BUT, I'm very sexual.
With this approach, I don't just get IOIs. I get asked for dates which I turn down occasionally. I also get indecent proposals from otherwise conservative women because I make them so horny and then play hard to get just for the fun of it.
Bottomline: I sarge them all as 'friends.' When someone asks me after a good fuck, "What are we?" and the girl insists on an answer, I simply reply, "You're a very special friend." This drives girls crazy and do more things to 'win' me over as a boyfriend.
Other PUAs around here will have their own game plans. Shop around for ideas and pattern something from those ideas that fits your lifestyle.
