Some of the Grab boys are very hot. I also often end up masturbating thinking of them.
But you can find similar boys on Facebook. Spend some time there, look at nice boys’ friends, and send some messages.
You can use Google Translate to write a short message. I always send the same initial message telling that I look for a top boy. And I got many really nice ones this way. Of course, many won’t reply. But once one replies it’s a very good sign… And you get something different than the bar boys.
