The reference suggests that Germans and Austrians are particularly fond of kissing. Therefore, based on the provided information, Austria and Germany could be contenders for countries with a high prevalence of kissing. However, it's important to note that this information is anecdotal and doesn't provide quantitative data to definitively state which country has the most kissing overall.
It is impossible to definitively answer this question without comprehensive data on kissing frequency in various countries, which is unavailable. Cultural norms, relationship habits, and even methodologies for measuring kissing would all impact the data, making it difficult to obtain and compare. The referenced text offers a cultural observation, not empirical proof.
