With the rise of only fans one thing that is made clear is that consumers want closeness and intimacy with their actors.
I think adding some videos that have ALOT more kissing with the camera and word of affirmation can be very successful.
Having stuff like "i love you" and other sappy stuff like that would be perfect and i think would be a popular hit. Adding scenarios like a wife a eagerly awaiting her husbands return and being very sensual slowly building up to a that fast and hard action everybody likes,
Or a couple falling in love for the first time and making out slowly turning hot and heavy and again building up to the finally.
It is very important to have close ups and lots of POV kissing in this as it gives the viewer a sense of closeness with the performer. I think words of affirmation and affection are also important but that's up to the actors.
