Be careful because there is a difference between mace and pepper spray. Generally, pepper spray is legal, but not necessarily so. Mace is often illegal, because it can cause reactions with certain people. Of course, pepper spray is pretty ineffectual, especially if you are not trained or ready to use it. Most people would benefit by not getting into certain situation in the first place. A big thing to understand is that there is a perception of American sexuality in the entire world which is not exactly true. Americans are quite open, forward, but not necessarily promiscuous. A lot of the body language we use without inferring much would be interpreted as an open invitation in most foreign cultures. If that can be avoided, by understanding cultural differences, it is better than relying on pepper spray which may or may not work.
