Yes, quite.

The question is more about tastes and habits. For example, to make a compliment to an unfamiliar girl or woman on the street - a norm of conduct for Cubans of all ages, an easy smile will suffice in return. This in no way should be regarded as an insult and sexual harassment.

At the same time in Cuba is quite common "free love" - ​​in society, relations before marriage are not considered something reprehensible. Moreover, sex tourism thrives in tourist areas, and demand (and supply) is not only for women, but also for men. Therefore, some modesty in behavior is preferable if you are not looking for adventure.

On the other hand, violence is virtually excluded, if you do not go to the deliberately unfavorable areas in the evening (there you will have nothing to do at any time, and any guide will remind you of this). By the way, if you plan to stay at the hotel - you may not be allowed to enter the room with a Cuban or Cuban.
