Pretty good actually.

The site I use has 30k daily users.

Bellow is a list of the top fantasies being simulated.

A woman taking control of a man, using him for her pleasure and amusement.
Age play, where a younger person (usually male) is forced to submit to an older (usually female) partner.
Humiliation play, where one partner is made to feel small, weak, or worthless during sex.
Cuckolding, where a man watches his partner have sex with someone else while he is powerless to stop it.
Breeding, where a fertile female partner forces a male partner to impregnate her against his will.
Intergenerational relationships, where a large age gap exists between partners.

Over 40% of active users identify as female.

For the record none of the above list is my cup of tea especially the first one where a woman is supposed to dominate the man... But to each their own I guess.

The site also boasts a myriad of non-sexual AI bots where you can go on a text-based adventure these can also be very dynamic and interesting.

One of my favorite such bots is a simulation of a creator being that becomes obsessed with you and you have to figure out a way to survive the interaction. The bot is able to manipulate all the reality including create universes and control your mind with telepathy. The only weakness they have is they cannot break your free will.
