Don't waste time with "sensual massage" places. If you want a massage, go to a licensed REAL massage place that does NOT offer extras.
If you want sex, then go to a prostitute. There are several all over the place. In Manila go to LA Cafe in Malate. In Makati, go to P. Burgos Street. But if you're looking for the best deal, go to Angeles City. Prices and selection are very good.
Don't try to mix massage and sex unless your girl happens to be a massage therapist. You will most likely get a horrible massage and rushed, unexciting sexual service.
Be sure you use protection because many Pinay in the sex trade are NOT educated about sexual diseases and have been used by many, many, many men who did not use protection.
Be safe and no matter what you do, PLEASE be kind and respectful to the women of the Philippines.
**Added... iyah, are you sure that thai massage... leviste st. salcedo vill makati offers "extras"? I thought they were a straight massage place. Maybe I'm thinking of the one on P. Burgos Street.
