>>63489519For the guy, it's honestly not much different than vaginal but with a lot of extra hoops to jump through. There isn't really much reason to obsess over it or care about it at all unless your lady is very into it and you're doing it for her sake.
For the girl it's stimulating a lot of the same areas as normal sex but just indirectly, so it just comes down to how they prefer things. Any girl can enjoy it as long as all the research and proper prep is done and you take your time to do everything right for them, but usually it's just a novelty and a trust-building exercise. And it can be utterly miserable or outright dangerous if things aren't done right.
