Indonesia's economy was already shaky, now with the Bali bombing, there are almost no tourists, especially in Jakarta. This means things are incredibly cheap, & you won't be competing with tons of other guys. If you're worried about safety, I have never had any problems, & actually find the locals both friendly & curious.

Club 40 is a typical Jakarta establishment, similar outside to a small shopfront with a big neon sign. Walk through the small doorway & upstairs into a bar area. Once your eyes get adjusted to the light, there are at least 30-40 girls hanging around. I liked the place as the girls don't hassle you, just cast your gaze upon them, walk over & say hello. The girls are young, beautiful, & willing. Ended up with 2 girls in their early twenties for a grand total of $US40 for the night. When we got back to the hotel, they were a bit nervous & appeared not to have done a threesome before. After a bit of coaching, we had quite a bit of fun. Next morning, another round of hide the sausage, gave them a couple of bucks for a cab, & a fun night had by all.

Indonesia has to have some of the cheapest & best sex available in the world, it certainly blows away anything I've seen in South America, Europe, or the USA.

Quick note on Jakarta. There is a bar located in Lokasari Plaza on the second floor out towards the car park.(Lokasari Plaza is a big center for cell phones and is located in the Jakarta district known as Mangga Besar)which is in the opposite direction of the area know as the M Block.
The name of the bar is Today Country, why I don't know since there is nothing country about it. But is just chocked full of sweet young things. They appear to be students there to make extra spending money and are chaperoned by mamasans. The place can be quite crowded during the 6 or 7 P.M. time period.
They have a set of short time rooms in the back and the best deal is to pick out a girl and find one of the mamasans to negotiate for you. Most of the girls don't speak much english but make up for it in the sack. Only short times with a shower first for her then you. Smallish beds and you have to pay extra for condoms, so bring your own.
Girls are really stunning but don't think that you can take them back to your hotel. It appears to be a short time place but with a lot of locals doing most of the action. Was kind of surprised at the number of "young" men frequenting the rooms in the back. At times you have to wait your turn for a room to open up.
Prices seem to run around $7 for the girl and $3 for the room but with the crazy 000000's on their currency I am usually out of the loop on exactly what it costs.
But if you are a short time type of guy this is the place for you. Tremendous selection and really some outstanding stunners. I am pretty sure that all the girls are of legal age since none of them had that really young appearance plus I don't think that the mamasan's would take the chance on underage girls.
Would love to take one back to my hotel for an all nighter but so far have never been able to get one of the mammasans to arrange it. But hope springs eternal and I will be going back.
