More power to you dv8...if that's your thing. I went through a similar stage of bragging about my conquests....but there were some very huge differences...I was in my late teens and twenties....these were my friends that I was speaking to....and I wasn't in a third world country PAYING for it. I had to work at getting the girl to 'put out'.... some a little more harder than others. But somewhere down the road I matured. Today even if I just finished banging a a few thousand pesos worth, I'm not walking up to somebody I don't know and this is the only subject I can manage to talk about. That's just plain old weird and possibly a sign of some sort of psychosis or self-esteem issue.
First point: it may very well be a self-esteem issue. Many men on the street here, because of poverty and lack of opportunities, will talk about these matters because it is the one thing they can be proud of.
Second point: unfortunately, a significant number of men visit the country looking for sex. So many local folks now assume a single foreign male who has come here is looking for sex.
Third point: many men who have low self-esteems come here for nookie because, for a few pesos, the working ladies will tell you that you are the sexiest, best-endowed, most handsome man they have ever met, or anything else you want them to tell you.
The best thing to do is smile and nod and pretend that you are jealous of the storyteller's prowess.
And if the story starts getting too much, stop the guy and say, "Que increible. Y todo el tiempo, yo pensaba que tu eras con el otro equipo." (Incredible. And all this time, I thought you played for the other team.") It's machismo, dude.
