Best Rum for romantic performance?

I was in the D.R. last week and those rums seem to have something special for performance. The local girl I was with in the hotel kept telling me "me quema el culo, me quema el culo"....I don't know what that means but I guess is good. Does anybody in here know something about this?

probably she had eaten some very spicy food and gone to the bathroom, because her ass is burning.

I think you mean Mamajuana. It's something like a rum liqueur. It is also available as a mix, but you have to find out for yourself whether it actually performes.
