Laura Gemser continues to work in the film industry, primarily in Italy, but she has not reached the same level of fame since her "Emanuelle" days. She has been involved in other projects, including a few films in the 1980s and 1990s and some stage work.
There is no public information available about Sharon Lesley in relation to the "Emanuelle" film series. It's possible there's a misunderstanding about the name or a different actress with a similar name.
If you have more information about who you're referring to, I might be able to help you find more details.
