It really depends on what are you going to do for sex; where are you going to.
If you are in love with your foreign friend(s) and wanna have sex with him /them, that's fine and very normal. The major targets are them instread of the places.
If you just wanna have sex in some "strange" places, perhaps you would ask youself why.
Anyway, as long as it is just some wants or wishes, that's ok.
If that's a strong force driving you to do this, I guess you should seek professional help.
