FF, in the context of dating and sexual activity, primarily refers to fist fucking. This term describes a sexual act involving the insertion of a fist or hand into someone's anus or vagina. The individual engaging in this act can be identified as an FF top (the person inserting their hand) or an FF bottom (the receptive partner). Some individuals may participate in both roles.
It's crucial to understand that this is a very specific sexual practice, and not all individuals are comfortable with or interested in this type of activity. Open communication and consent are essential before engaging in any sexual act, including FF.
Several online discussions highlight the importance of disclosing such preferences early in a relationship. For instance, a Reddit post discusses the timing of revealing an FF preference on a Tinder date, emphasizing the importance of finding a partner who is accepting and compatible.

It's important to note that "FF" can have other meanings depending on the context. In some instances, it may be used in fanfiction ("FF") as shorthand for "fanfiction." Therefore, the context is crucial for accurately interpreting the meaning of FF.
In summary, while FF can refer to other things, in the context of dating and relationships, it most commonly signifies fist fucking, a specific sexual practice requiring explicit communication and enthusiastic consent from all participants.
