You need to decide whether you are looking for sex or a relationship. I suspect that you really want a relationship, or at least want both. However, you are looking solely in a market whose primary purpose is to provide sex and sex only. You may not even have the filters to be able to selectively chose those few working girls who would be inclined for a normal relationship.
Personal recomendation is to start dating A LOT! Don't go into it like most guys, desperate to get some pu*sy. You already know of an abundant source for that. Just go out on a lot of dates with a lot of women (yes EVEN GRINGAS). Sign up to a bunch of dating sites. No matter how you look, you are going to get a bunch of rejections, but also a bunch of yeses as well. Date pretty girls, ugly girls, thin girls, fat girls, whatever. You'll find a good portion of your relationship cup will fill rather quickly. More importantly, you will discover what you want, rather than falling for the first puta that is nice to you.
Don't worry about the falling in love thing, man. It happens. My first trip to Latin American I fell for a chica. Probably the best thing that could happen to improve my mongering skills. That girl gave me a PhD in Chicaology in about 7 days. Hell, I should be sending that little hottie a thank you card every year.
