Marriage!

[Elianna]

As for Galadriel and Celeborn, the answer could simply lie in surprisingly limited choices. Assuming she married after leaving Valinor: All the Vanyar were still in Valinor. Of the Noldor, elves of the House of Finarfin are excluded (too closly related, duh), and she was "unfriends" with Fëanor, so his desendants were also excluded. This leaves the House of Fingolfin, to which she probably felt herself too closly related to.
That leaves the Teleri. In the standing of Teleri, Celeborn was high up, Thingol's nephew. (Of course, being Thingol's nephew makes Celeborn and Galadriel each other's first cousin once removed, which is still too close if you ask me, but oh well.)

That's only Orli-Lego. There were plenty of masculine elven men. Gil-galad, Celebrimbor, Thranduil, Echthelion, Glorfindel......

As for Melian..............she was just weird.........
