If she's a novia of a friend, the answer is no. Bro's before Ho's. However, if she's a favorita of a friend who is not with me on the trip, I see it differently. She's still a working girl so why would I not go with her.
Now to a true story... Several years ago, the "mayor" of Barrio Amon/Atoya introduced me to a delightful young chica, new to the biz. Soon after she was homesteaded by a guy living in CR whom I had met but did not know. When I saw her at Halloween 2012, she looked wonderful and radiant since he was taking good care of her. Soon he kicked her out since she got pregnant by a Tico boyfriend.
For Halloween 2013, I sent her an email that I was coming down and would like to see her. When I saw her at the SL, she was with a guy who had brought her an ipad and was planning on homesteading her when he retired from NY. I thought "Oh well, there are other cuties around." By 10:00 PM that night she called me and asked if I still wanted to see her! She dumped the guy who brought her the ipad, but brought the ipad with her!
She ended up staying with me all weekend and at the SL Halloween party, I felt awkward since both guys who had homesteaded her were there, even though I did not know either guy very well.
On my recent trip, I sent her an email and when I called her she was immediately ready to come see me! I was a bit surprised since the "mayor" had told me that she had a new boyfriend from Louisiana who had bought her a ring and wedding dress and had applied for a Fiancee VISA to bring her to the US! I had a good time with her, but decided against seeing her again. She spoke freely to me about the guy in Louisiana who wanted to marry her. She did not seem either excited or apprehensive. She's more than a bit screwed up in the head now. In fact the next night I saw her walk in to SL with a really old Indian dude that I had never seen before and head to his room! Maybe he will also be trying to homestead her soon.
My point of this story is that for most chicas if she has a gringo who likes her and is supporting her, she's still likely to be seeing other guys while he is not in town, and maybe even while he is in town. It's just the way they seem to view life.
In the last 3 years, this chica had 3 different guys try to homestead her and each time she has not valued that at all. Hell, I even had fleeting thoughts of homesteading her. What adds to the confusion is that she comes from an intact Costa Rican family, speaks English very well and seems to have more class than many of the chicas I see in the gulch.
My bet is the guys living in CR can confirm this is more the norm than unique.
