Whenever the natal ruler of your 5th or 8th house is transiting on your ASC, 5th, 8th or 12th house, it rises your levels of lust.
Hard aspects create friction and an instant urge for sexual activities without much patience, such as having a one night stand, a fling, an affair,…
Especially when it involves the 5th house, this is the house of one night stands.

Uranus :
Uranus transits may also trigger a sudden boost in sexual urges.
When in a harmonious aspect to one of the love/sex related planets, it could bring a new relationship that blossoms out of a sexual adventure, however it’s longevity is unpredictable and rather unsure since it brings two people together who would otherwise not get together. When Uranus makes a hard aspect it could point out to a one night stand or a sexual adventure that leads to nothing more than just a quick pleasure.
IF a relationship comes out of that, it may not be of longterm anyway and the relationship will be colored wit unpredictability.

Neptune :
When Transit Neptune is involved with one of the love/sex related planets, it creates illusions in which the feeling with reality is vanished or disturbed, especially when Neptune makes a hard aspect : Conjunction, Square or Opposition. It’s hard for the native to think rationally towards sex and is more likely to reach instinctively/animalistic when a sexual opportunity arises, or the native might indulge into gooning/edging for hours watching porn for example.
Neptune in harmonious aspect may bring an amplified need for romanticism and sensuality, a deep need to merge with another person into a sexual act. Almost as a way of escaping the daily routines.
