I used to work as a bouncer on a club here in Mexico City for reference and girls used to tell me all the time (at least 2-3 girls a day) was hot as fuck, asking for my phone number, grabbing my ass, asking for pictures with me, etc... while on normal day to day life, things like that happen to me, but much less frequently, I think it depends on the context, situation, etc but at least I can tell that in Mexico that is a pretty westernized society women do it all the time and guys too, I dont think its innapropiate but it depends om the context
