2. (slang) first sexual relations, one's first time

/uɸi/ → /uwi/ → /ui/

First attested in the Kokin Wakashū of roughly 905-914 CE,[2] and assumed to be inherited from Old Japanese.

There is an apparently related term 初 (ubu) of overlapping synonymous meaning, first attested in the early 1000s. It is unclear how these two terms are related: one might be a derivation of the other, or the two might derive separately via other processes.

Both ui and ubu appear to be related to verb 生む (umu, “to birth”), from the sense of "first of something since one has been born".

Martin suggests that this might be a fusion of 生む (umu, “to birth”) +‎ 日 (hi, “day”), literally “birthday”.[3] However, the meaning of any such compound would be the noun birthday with a sense of "the day a woman gives birth" rather than "the day someone is born". Also, phonologically, this would be expected to result in ubi: /umu/ + /pi/ → /umupi/ → /umpi/ → /ubi/.

Possibly cognate with 上 (ue, “above”, possibly via the sense of "upstream → earlier") or classical verb 生ふ (ancient opu, classical ofu, modern ou, “to grow”).
