Well Gabriel - what exactly have you done to look for other tickle lovers? I'm not a pro. I've had my own problems looking for others out there. I imagine if there were others in Puerto Rico, you should have found them here on the forum. 
The only advice I can give you is to change your focus, instead of looking for people like you who love tickling, just look for regular people and get them into tickling. I've had more fun this way. I've been a TMF member for over 10 years, and haven't met anyone in real life anywhere, let alone close to me. BUT, I have talked to girls about tickling and convince a few to try it out. 
So go out there and meet people. Be honest and confident. They're more open-minded & tolerant than you may think. Hope it helps. Good luck
