a brand new and rather interesting and different massage place has opened about a month a go on Ratchada Soi 3, next to R3 Sauna, specializing in "sexual health .with prostate, testicles and tantric massage". This is interesting, as for some reason male massage places are not offering these services. There is a straight girl massage place in Sukhumvit 22 specializing in prostate massage, one in Silom Soi 6 (named Ben Ten) spezializing in testicles massage, and one more or less gay palce (Spa Bankgok) doing tantric massage.
Might try this one today.

I've been to Angkor, but judging from pictures Borobudur is rather different. I shall see....
