Just noticed this thread and would make the point that if you travel in the far east or closer to home and are caught trafficking you may face stiff penalties up to and including death ,this is widely known and publicised I have never however seen this warning about adultery on any tourist site or Filipino embassy site and in my view this is the problem.
All countries are free to have whatever laws they like (as long as it doesn't interfere with oil)but they should be proud enough to publicly shout there "Moral high ground " position so that it is clear to us and we can then not get inadvertently put in the position of breaking them through ignorance or become victims of a shakedown.
