It is interesting on this board as it seems there are mongers and there are the morally righteous people here. I used to be apart of the World Sex Guide, and we were all mongers, just like another board I am on that talks about Angeles City in PI. I just thought Tokyo Adult Guide meant just that, an adult guide for us sex starved folks (men and women) in Tokyo. Maybe I am way off base, and sorry if I am. Not here to make waves.
50% is a good ratio. 90% is really good and just bragging I feel. If you are that much of a nampa machine, you need to post some non nude and nude pics here so we can see the carnage and hail your abilities. It is like guys who are bragging for picking up cute girls in Angeles City or Bangkok/Pattaya and saying they are the shit in mongering for picking up a girl for $30 USD's. Again, not here to make waves but being a monger does have responsibilities.
I don't know about you guys (women?), but doesn't the whole 自己紹介 get redundant with nampa? In response to kristov86, yeah it does get repetitive and tiring. I much rather drop 20K-25K JPY and just do my deed without all the bullshit. If you are going to do nampa then you are going to burn that and more in money and time spent....
On this statement about nampa...
Nampa is more cost effective when spread out over multiple dates or per the hours you spend together on a single date (like all night and until early next morning)
For example, I tend not to take women to the house on the first date, to filter out psychos. So hotels, happening bars, their house, etc...
Hotel, clubbing, and dinner can get in the 20,000 plus range in Tokyo, BUT if ONLY you are paying and this tends towards 1st dates. HOWEVER, It can happen that you strike out 3x or so. Thus it's possible to pay 60,000 yen ($600 ) in Tokyo for dates with 3 different women or 1 woman that you struck out on 3x.
Striking out and paying the entire cost of the date is where it can be expensive. But usually a strike out doesn't make it to the hotel, just dinner and clubbing, so around 15,000 yen ($150). A guy can keep it way cheaper than that, but assuming he doesn't mind coming out the pocket a bit.
I date various age ranges, so I would pay all of the date when with like a 21 year old college student, but I would expect a 31 year old working women to pay 20% to 50% of the bill. If she is wearing all kinds of expensive jewlery and designer clothes, and confesses to having money during our drink and dinner conversation, then possibly more than 50%. So on a "strike-out" date, I can usually keep it under 10,000 (100 dollars), with the lady offsetting some of the cost. Let's put that at around 1/3 on average.
On subsequent dates, there is a tendency to go to her apartment or mine, instead of the hotel. This significantly REDUCES costs. Often to 7,500 (75 dollars) or LESS per dinner date. Her offsetting the cost a bit, 5,000 (50 dollars) or less.
If you have your own place, it can be very cheap, where the woman comes straight there. Thus it's minus some food and drink in the refrigerator (maybe 2,000 yen ).
And if the hotel, married women and college students tend to be fine with short stays (2 to 3 hours), which can be 4,000 (40 dollars) or less. For working women, they are often fine with short stays at the hotel on weekdays, if there is some reason not to go to your place or hers. So dinner and short hotel stay where ONLY the guy paid would be around 12,000 yen (120 dollars) or less (often less). Less than 10,000 yen (100 dollars) if she offsets the cost a bit.
Time wise, it's actually almost the same for searching on the Internet. Sending chain e-mails to various Internet dating sites is about the same as looking for attractive women on escort websites, once you have created a template message and/or setup a profile. Sometimes women message your profile...
Street nampa, once you have skill, isn't difficult once you lose the fear of rejection. You would talk to women on your way to and from work. So not really putting a burden on your time.
Even if you travel around looking for women, where it might cost you time, the money spent is none to little. So nampa is more about effort, than expense.
I do agree that P4P excels in avoiding the crap that many women dump on men. Games, manipulation, neediness, arguments, sneakiness/cheating, difficulty in establishing and breaking off the relationship.
But even this too is offset by regular "non-pay" relationships being "more real", emotionally fulfilling, or being able to do more things sexually with the woman (provided you pick the right ones). And if you are dating multiple women at the same time, a guy can dump the more annoying women and replace her with ones that are less so.
Overall, I think the ROI (Return On Investment) depends on the mindset and willingness to put in the effort by the guy. Both have pluses and minuses that can make either direction very comparable to each other overall.
