am looking to go on a trip to BA and wanted to know. Will all the woman be open to anal sex?

On average, if i go for 6 days/5 nights and expect to have a woman all night every night and some day action on the side, how much money can i expect to spend?

I can't give definitive answers but I can provide partial answers.

For daytime and early evening activities, there are many casas that span many prices. Generally, I have had good luck at some of the casas in the 200 peso range (per hour) and spotty luck at those that charge 100 pesos or less.

As to anal, it seems to be widely available at the casas BUT at many of the less reputable casas, which constitute perhaps 1/2 to 2/3 of the hundred or so casas in Argentina, they will promise it to you, collect the extra money, and then renege once you are in the room; if you like hearing that your dick is too large for anal, no matter whether it is true or not, Buenos Aires is a great place to experience.

Having said this, two casas that seem reliable are located at Diagonal Norte 885, piso 3 G (website: www.templomarion.com) and Santa Fe 2036, piso 2 B (website: www.bonnefemme.com.ar). The former charges 200 pesos an hour, anal usually included (you should ask about the particular girl before choosing) and the latter charges 200 pesos an hour with a surcharge of 50 pesos for anal (again ask in advance). Diagonal Norte has a "sister" location at Maipu 429, piso 5 5 which charges 150 pesos so if you don't find something you like at Diagonal Norte (they usually only have three girls on duty) you could visit the Maipu location to see whether they have something more to your liking. However, the price difference between the two places reflects that the girls at Maipu tend to be less attractive.

Incidentally, the pictures on templomarion's website spans both locations, Diagonal Norte and Maipu.

A cheaper place where most of the girls do anal is Uruguay 343, piso 1 (http://www.gozanos.com.ar/) which is 100 pesos per hour.

The pictures on the websites of the two more expensive places are reasonably accurate (although Barbie at 2036 Santa Fe has put on a lot of weight and no longer looks good at all) while most of the pictures from Uruguay 343 are far less than accurate--damn Photoshop). Also, Uruguay 343 is VERY busy, meaning your chance of getting one of the better looking girls there on a particular visit is often slim. Many customers reserve in advance but this is dangerous if all you have to rely on is the photoshopped photos on their website. It really is justified only for repeat sessions.

Moving to all night activities, although I don't usually hang out at the clubs I believe most are geared to two hour or so take out, not all night. Also, it sounds like many of them are getting exceedingly expensive, but again, I am only relying on what I hear as I don't usually bother.

The one thing you should no about Buenos Aires is it is much more mercenary than Brasil, thereby making it a bigger challenge to have fun there.

TLN/LT is harder to come by in BA than in places like Rio or AC as most of the girls live in BA and have a local life to take care of. There are a lot of girls from Paraguay and they tend to be more open to it. But unless you take a girl out of a club after 2 or 3am, they figure they can go back to the club and get another guy. Plus, the club expects her back unless you pay for multiple lady drinks before you leave. You are better off thinking of BA as an ST kind of place rather than expecting LT to be the norm.

For two girls a day, you are going to spend around $AR500-600. But you could spend as little as $AR120 (two apartment visits) or as much as $AR1000 (high end apartment for $AR200 plus a girl from a high end club like Black for $AR600+drinks).

Hotels and meals have gotten expensive over the last few years. Figure a bit less than you'd spend in Rio/SP.

As far as anal goes, YMMV. Always ask if they are "completo" before closing the deal. I'd say it's less common than Brazil but it's still available.

> they will promise it to you, collect the extra money, and then renege once you are in the room

Well, I guess there's some comfort in knowing that it doesn't happen to only me.

I stopped using the term 'completo' outside of Rio, and now use more explicit terms. Twice when I bargained for completo, and both just happened to be in Curitiba, it turned out it meant massage+sex. Maybe that's what it means in Curitiba. I can't recall trying use this term in BA, rather 'en la cola' to avoid misunderstanding.

The Paraguayan gals in BA had such shitty attitudes that I put off an excursion to that country. Some fine looking specimens, though.
If you're looking for something on the seedy side, there are a lot of street walkers from Dominican Republic. I put up a trip report on the low side of BA a few years back, it might still be available.
