I do not think it is a myth and I think STD's are a problem everywhere!
I think that most Domincians use condoms (when they can, when they have money) but it is very hard to give any reasons why or why not people do not use condoms. I do not know if the chicas have a higher rate of STD's than the chicos. statistics are needed!
I do know of a girl that was in DR with her Dominican boyfriend. Went home to Canada and realized that she had a STD. She took the necessary medication to clean it up and brought some medication for her beau in DR. If she were a little more attentive to the situation she would realize her boyfriend sleeps around, not only when she is away but when she is living with him in DR. She is still involved with him and quite naive as to how she got the STD in the first place. GO FIGURE?!?!
Another tourist I met was getting tested for HIV and Hepatitis since her lover told her 2 years after knowing one another that he may be infected and she better get checked out. HELLO???
This does not make sense.
Testing should be done before you get invloved in a long term relationship - if you are just having a fling, insist on condoms and save your life. I think Domincians are just as aware of STD and HIV as others in the world and like them, take precautions to avoid getting infected but like others in the world there are some that dont care and dont want to know if they are sick or not.
STD's and AIDS are a risk anywhere you go!
My 2 cents worth
