Muslims account for over twenty percent of the population of the world and more than that fraction of prime-aged girls. For religious and cultural reasons these girls tend to be quite inaccessible to outsiders and often have their romantic and sexual choices restricted or simply made on their behalf.
A high proportion of Muslim girls, families, and communities take religious and cultural practices and rules seriously. These practices include an outright ban on romantic and sexual contact with non-Muslim men. That makes them a difficult, but not impossible challenge for an outsider. The journey to success with a Muslim girl is often challenging but can be a rewarding one.
All points are generalizations only, based on the personal experiences of the author, who is not a Muslim. As with any other religious group there is a high level of variation between individuals within that group. These points should only be seen as tendencies to look out for and warnings of what to be prepared for, not as certainties.
