The Xenomorph - Asexual and bloodsucking?

Asexuality
In Alien, the xenomorph is clearly not mating. What it does is probably transferring its DNA through its secretion when building a nest? When a victim is placed in the secretion structure it is dissolved and transformed into an egg (if we go by the director’s cut, that is). Otherwise, a queen would be needed (which is also asexual)?
Bloodsucking
I don’t believe we have seen a xenomorph eating, have we? In Alien, it killed Brett, Parker and Lambert (but kept Dallas alive in the nest). It kills its victim by stabbing it with its inner jaw so that the victim’s blood spurts everywhere. Perhaps the xenomorph drinks it? All the victims are intact (except for the spurted blood).
The only possible proof of this thesis might be the neomorph? After having decapitated Rosenthal with a powerful bite in the neck, it sits on top of the body and seems to be feasting in the blood spurting out from the neck? It is drenched in blood when it comes towards David.
