A noun appearing as ᴱQ. puhta or pukta (the second possibly a primitive form) in Early Noldorin Word-lists of the 1920s as the cognate of ᴱN. hoith “coitus” (PE13/147, 163), probably derived from a variant form of the early root ᴱ√PU(HU) “generate” (QL/75).
Neo-Quenya: I would retain this word as ᴺQ. puhta “coitus, ✱sex” for purposes of Neo-Quenya based on a Neo-Root ᴺ√PUK for Elvish “sex” words.
A verb appearing as ᴱQ. pukta- in the Qenya Lexicon of the 1910s under the early root ᴱ√PU(HU) “generate” (QL/75). According to the editors, it was written over an erased word whose glosses seems to have been “coire”, which is Latin for “to copulate”; elsewhere derivatives of this root had to do sex and sexual organs.
Neo-Quenya: For purposes of Neo-Quenya I would adapt this word as ᴺQ. puhta- “to copulate, have sex” as suggested by Fiona Jallings, with the later Quenya sound change of kt to ht.
