I'd venture that forced sex/CNC is appealing in some form to a lot of people.

I've not heard of it from this perspective of wanting to feel so desired that their partner couldn't control themselves. However, I have seen a lot of discussion that it's fairly common for people who grew up in a strict religious environment that was very anti-sex. They want sex, but they feel guilty enjoying sex or letting themselves have unmarried sex, so when it's a forced sex/CNC scene it allows them to enjoy it because that fantasy alleviates the guilt and let's them let go and enjoy sex since they're not choosing the sex, it's being done to them.

It can take on a variety of forms and intensity, but at any level it definitely requires a lot of trust and communication. Especially if it's the first time for both of you. General BDSM etiquette applies - the one being dominated needs to be able to trust that their partner will stop immediately if needed. The one dominating needs to be able to trust that their partner is willing and able to speak up and use the safe word when needed. I don't recommend going from zero to a really intense/violent scene. Start with something small, a single act, and then come together and discuss how it felt for both of you. It's also really important to know what kind of aftercare you both need. It can be easy to assume that the one being dominated needs the most aftercare, but it can be really hard on both of you so you both need to advocate for what you'll need from each other after.
