"Your first time" in mainstream tv & film

EXPLICIT CONTENT 

Those who are familiar with the forums dedicated to pornography, or just nudity in tv and film, in general will notice one thing: the excited anticipation of a pornstar's first anal scene (nowadays it's the rise of cuckoldry with black sexual partners). The discussion goes something like this.

Person A: I cannot believe Amy Star [fake pornstar stage name] hasn't done anal yet. It's been four years!

Person B: It's not if, it's when.

Person A: I just can't wait for it to happen. Same with her first *interracial scene.

Given the scenario above it's almost identical to those who wish to see a certain actress nude, whether it's s throwaway nude scene (i.e. dressing/undressing, shower or bathing, topless sun bathing) or a sex scene (explicit or not). See below.

Person A: Has this actress done any nudity yet? She has a great body and hella cute.

Person B: Not yet. It's only a matter of time. Some take longer than others, but it'll happen eventually. She just needs the right role for it. 

If the pornstar has done one anal scene then more than likely she'll be open to do more anal scenes. This is usually the case. Same thing with actors who have done nudity and/or **sex scenes - all they need is that one scene and that'll leave the doors open to more nudity and sex scenes as long as they act. 

Talks amongst female actors usually end up like girl-talk of "when was your first time" (on screen versus in one's own sexual life) mainly because sex scenes are innately treated like such talks. During an actors' round table, actress Jennifer Lawrence recalled her first sex scene to which, quickly, Cate Blanchett responded for clarifcation "your first sex scene on film?" Of course the latter knew what she was talking about, with the question made in light jest, but the topic could have been easily directed towards the losing one's virginity in real life. Hmmm. Interesting. 

First film/tv sex scene oddly resembles talks of one's first time having sex in real life ... 

*Interracial sex in pornography: In mainstream tv and film actors doing gay/lesbian/bi roles that involves sex scenes (explicit or not) are seen in the same light. In fact, it's now seen as a "check mark" role to get out of the way, like in the 2000s to play an oppressed Jewish person in order to get an Oscar nomination.

** Rarity, some actress have done sex scenes who were not nude. Case in point Saoirse Ronan. Her earliest intimate scene was in The Host where she wore a sports bra (it wasn't a time period film). Her other sex scenes, one with Kate Winslet in the lesbian movie Ammonite Ronan was also fully clothed (time period piece where she was given oral); and another in Brooklyn - also clothed in which the sex scene was amazingly tame despite her character having sex with her boyfriend, though it was in a more socially conservative time period. In The Host I believe she specifically noted she didn't want to get nude - whether be nude for the scene itself to be filmed or nude in general where her hair or bedding would cover her breasts between her co-star. Other sex scenes were in Queen of Scots and Lady Bird, both of she again was clothed. 

Currently, she and Watson are the only actresses that I know of, with their establishment, who outright said no to nudity or made the potential of nudity to zero as they convinced producers to be clothed for such scenes. For Watson, she had a body double in Regression.
