I found Czech and Slovak boys to be basically sexual and uninhibited. You can have a torrid session with one of them, where he kisses you passionately, rims you, sucks you to completion, swallows your cum, or even bottoms for you, after which he might go fuck his girlfriend. Amazing kids, with no hang-ups whatsoever when it comes to sex.
I agree about his butt, @meluvjan02, but I didn't try. He told me that he prefers to top, but I am sure he wouldn't refuse to bottom, maybe for more $$. Just ask.
