Welcome back, @Bluenova 
Sexing living tarantulas is difficult as they tend to wriggle. Do you have an exuvia, an empty skin from your tarantula's last growing phase? Then look between the hind legs on the belly side: if there is a flat and rather hairless spot, about semi-circular, it's a male. In large adults you can often see the bulbi - penis-like structures on the ends of their feelers. Those are usually worn folded up like a pocket knife, so that they are difficult to see. With almost all south american species the males have an additional claw or thorn-like structure on their shins.
If area between the hind legs is hairy and slightly raised (not flat) and if you can see a furrow in it (only in adult spiders) it's a female.
@think while I wouldn't go so far as to eat one of my partners, there are men I'd have appreciated to die after sex. Or before, rather, in at least one case...
Most spiders males over here get away. Being eaten is more an exception than a rule for European spiders. Nature always follows the principle "waste not, want not" and thus reuses perfectly good males. Makes sense in a genetical way, too: a wider mixture and more new combinations improve the genetic stability of a population and increase the chance for new and successful variations.
