Oh god, do we really want to have the smells of sex when watching porn?

On the other hand, I see an opportunity even without tech: porn star perfume collabs: Spray some Gukki Bloom and press play on that video to smell what the star was wearing on the day.

But I guess high-end perfume brands don't want to be associated with actors of the flesh.

No, you want the smell of your ideal partner.
