I don't know if any of you guys have seen this movie from Argentina.
Actually, it has been posting several times on this forum. It is called Burnt Money (Plata Quemada):
https://www.imdb.com/title/tt0227277/?ref_=nv_sr_srsg_0
The thing is that it has a hot scene where "El Nene" is having sex with a woman he came across. In a conversation between them, she realizes how much he loves his partner: Angel (he talks about him as he were his twin), but Angel has a mental disorder. That, drugs and the fact that Angel is privet him from sex due to a sort of superstition towards semen, apart from the creasing attraction he's feeling for this woman, is that they ended up fucking.
She knows Nene's feelings for Angel, but she hopes he leaves him for her.
The scene begins at 01:06:30
Sorry, I didn't find it with better video quality, nor English subtitles, but I hope you can find it by other means.
